kondaur [170]

Answer:

(x = -6), (y = -6)

(-6,-6)

Step-by-step explanation:

X=-6

3x - 2y = -6

3(-6) - 2y = -6

-18 - 2y = -6

What you do to one side, you do to the other. And when you take it over to the other side, you'll have to turn -18 into a positive 18.

-2y = 18 - 6

-2y = 12

Divide both sides by -2

y = -6
