Question

Solve by the elimination method
3x-7y=15
-5x+4y=-25

Answer 1

multiply the top problem by 5 the whole way through and the second one by 3 to elimate the x and then we will solve for y

Answer 2

15x - 35y = 75
-15x + 12y = -75
-----------------
-23y = 0
y = 0

3x - 0 = 15
x = 5

Answer 3

therefore you will have:
15x-35y=75
-15x+12y=75
0 -23y=0
y=0
-5x=-25
x=5

Answer 4

thanks
