Answer:
(-6,1)
Step-by-step explanation:
-2x+6y=18
-4x-6y=18
Add the two equations together to eliminate y
-2x+6y=18
-4x-6y=18
--------------
-6x = 36
Divide each side by -6
-6x/-6 = 36/-6
x = -6
Now we need to find y
-2x +6y = 18
-2(-6) +6y = 18
12 +6y = 18
Subtract 12 from each side
12-12 +6y = 18-12
6y = 6
Divide by 6 on each side
6y/6 = 6/6
y = 1
