1.What is the solution to the system of equations?

x + 2y = 4

4x - 2y= 16

2.When you are using the elimination method, what must you multiply the 2nd equation by so you can eliminate the x?

10x - 6y = -5

5x + 4y = 6

3.What is the solution to the system of equations?

2x - 2y = 6

7x + y = 19

4.
