19. Solve each of the following systems by elimination. Check your answers by graphing, and paste a screen shot of each graph with the solution shown. a. 3x – 12y = 25 b. .5x = .25y . 2x – 4y = 7 x + 2y = 30. 20. Systems in three variables can also be solved by using the elimination method. Work with any two equations at a time.

Elimination Method. We will add or subtract our equation together to eliminate one variable. Why is this legal? Solve for the remaining variable. Using the value you found, plug into an equation and find the other variable. Ex. Using the Elimination Method. Solve the system using the elimination method. x + 2y = 10. x + y = 6. 2x + 3y = 12. 5x ...

Systems of Linear Equations: Elimination by Addition Method. First, let's look at a system of 2 equations with 2 variables: = = The general idea is to add a "multiple" of one equation to another equation in such a way as to eliminate one of the variables. Note that a "multiple" of an equation is just a nonzero constant times an equation.
