Answer:

(-1,-1)

Explanation:

-3x+8y = -5

6x+2y = -8

Multiply the first equation by 2.

2(-3x+8y = -5)

-6x + 16y = -10

Add this equation to the second equation and eliminate x.

-6x + 16y = -10

6x+2y = -8

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

18y = -18

Divide by 18.

18y/18 = -18/18

y = -1

Now we can find x.

6x+2y = -8

6x+2(-1) = -8

6x -2 = -8

6x = -6

x = -1

The solution is (-1,-1)
