Which graph represents the solution to the given system? -4x+3y=-12 and -2x+3y=-18

-4x+3y=-12 
-2x+3y=-18
for this problem i want to eliminate so im going to multiply the second equaion by -2 so i can eliminate the x values and get a new equation of : 4x-6y=36

now you can eliminate
    -4x+3y=-12 
 +  4x-6y=36
         -3y=24
           y=-8
now that you have the y value so its easy to find the x, by plugging in -8 for y in either of the equations

4x+3(-8)=-12
4x-24=-12
4x=12
x=3

(3,-8) 

Xis equal to three
