Answer:

x=0 , y= -2

Step-by-step explanation:

6x-9y=18

-6x+2y=-4

Add the two equations together to eliminate x

6x-9y=18

-6x+2y=-4

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

    -7y = 14

Divide each side by -7

-7y/-7 =14/-7

y = -2

Now we can find x

6x - 9(-2) = 18

6x +18 = 18

Subtract 18 from each side

6x+18-18 = 18-18

6x = 0

Divide each side by 6

6x/6 = 0/6

x = 0
