Answer:

x = 3, y = -3

Step-by-step explanation:

3x - 2y = 15 (eq 1)

x + y = 0 (eq 2)

(eq 2) x 2

2x + 2y = 0 (eq 3)

(eq 1) + (eq 3)

5x = 15

x = 3

SUB x=3 into (eq 2)

3 + y = 0

y = -3

Positive 6.8, because when numbers are next to each other with a parathesis being the only thing between them, all you have to do is multiply. Because they are both negative as well they'll cancel out or make the product/answer positive.
