Answer:
x=0 , y= -2
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
