1. What could you multiply the second (purple) equation by to make the y-values additive inverses? (See photo 1)

2. What could you multiply the top equation by to be able to add the equations and eliminate the x-values in this system? (See photo 2)

Answer 1

Answer:

1. multiply by -2

2. multiply by 3

Step-by-step explanation:

1. 3x-4y=-5

5x-2y=-6

multiply the second equation by -2 to get 4y.

-10x+4y=-12

2. 2x+5y=5

-6x+7y=-37

multiply the top equation by 3 to get 6x

6x+15y=15
