Which constants can be multiplied by the equations so one variable will be eliminated when the systems are added together? The first equation can be multiplied by -12 and the second equation by 5 to eliminate x.
How do you get rid of a variable in an equation?
The basic technique to isolate a variable is to “do something to both sides” of the equation, such as add, subtract, multiply, or divide both sides of the equation by the same number. By repeating this process, we can get the variable isolated on one side of the equation.
What does it mean to eliminate a variable in a system of equations?
In the elimination method you either add or subtract the equations to get an equation in one variable. When the coefficients of one variable are opposites you add the equations to eliminate a variable and when the coefficients of one variable are equal you subtract the equations to eliminate a variable.
What happens if all the variables cancel out in an elimination equation?
If both x and y are going to cancel out, then you have either no solution or infinitely many solutions. If the constant on the right are going to cancel out (same number with opposite signs) then there are infinitely many solutions (same line).
What happens if both variables are eliminated?
If both variables are eliminated and you are left with a true statement, this indicates that there are an infinite number of ordered pairs that satisfy both of the equations. In fact, the equations are the same line. Solve for x and y.
How do you get rid of one variable in an equation?
In the elimination method you either add or subtract the equations to get an equation in one variable. When the coefficients of one variable are opposites you add the equations to eliminate a variable and when the coefficients of one variable are equal you subtract the equations to eliminate a variable.
How do you cancel out a variable?
Elimination is a method for solving linear equations by cancelling out one of the variables. After cancelling the variable, solve the equation by isolating the remaining variable, then substitute its value into the other equation to solve for the other variable. so that both of the coefficients of u200bxu200b are u22121.
How do you get rid of a variable in two equations?
RULE #2: to move or cancel a quantity or variable on one side of the equation, perform the “opposite” operation with it on both sides of the equation. For example if you had g-1=w and wanted to isolate g, add 1 to both sides (g-1+1 = w+1).
What is elimination in systems of equations?
The elimination method is where you actually eliminate one of the variables by adding the two equations. In this way, you eliminate one variable so you can solve for the other variable. In a two-equation system, since you have two variables, eliminating one makes the process of solving for the other quite easy.
What does it mean to eliminate a number or variable in math?
more … To remove. In Algebra, when we have several variables (like in a System of Equations) we can sometimes eliminate a variable by doing things like adding equations.
What does it mean to solve a system by elimination?
To Solve a System of Equations by Elimination Make the coefficients of one variable opposites. Decide which variable you will eliminate. Multiply one or both equations so that the coefficients of that variable are opposites.
What does it mean to eliminate a variable and why is that useful in solving a system of equations?
When we use elimination to solve a system, it means that we’re going to get rid of (eliminate) one of the variables. So we need to be able to add the equations, or subtract one from the other, and in doing so cancel either the x-terms or the y-terms.
What happens when the variables cancel out?
In general, if you have an equation in which all your variables cancel out, then it tells you that your equation is either true or false, independently of the vaues your variables take. In your example, you arrive at the equation 0=1, which is false. No matter what values you take for x and y, it will never be true.
What happens when both variables cancel out in elimination?
If both variables are eliminated and you are left with a true statement, this indicates that there are an infinite number of ordered pairs that satisfy both of the equations. In fact, the equations are the same line.
What happens if the elimination method results 0 0?
If you end with 0=0 , then it means that the left-hand side and the right-hand side of the equation are equal to each other regardless of the values of the variables involved; therefore, its solution set is all real numbers for each variable.
What is the solution if all variables cancel when solving a system and you are left with a false statement?
If both variables drop out and you have a FALSE statement, that means your answer is no solution. If both variables drop out and you have a TRUE statement, that means your answer is infinite solutions, which would be the equation of the line.
When both variables are eliminated resulting in a false statement the system has no solution?
If both variables drop out and you have a FALSE statement, that means your answer is no solution. If both variables drop out and you have a TRUE statement, that means your answer is infinite solutions, which would be the equation of the line.

Solve Systems of Equations by Elimination – Elementary Algebra
We can make the coefficients of x be opposites if we multiply the first equation by 3 and the second by −4, so we get 12 x and −12 x. This gives us these two new equations: When we add these equations, the x ’s are eliminated and we just have −29 y = 58. Once we get an equation with just one variable, we solve it.
