Question

Solve system by elimination
-9x+7y=22
9x-5y=-26

Answer 1

The solution would be (-4, -2)

Explanation:

To find this simply add the two equations together.

-9x+7y=22

9x-5y=-26

----------------

2y = -4

y = -2

Now we have the y value, we can solve for the x value.

9x-5y=-26

9x-5(-2)=-26

9x+10=-16

9x=-36

x = -4
