Okay, inorder to do the elimination process here as ajprincess mentioned above you multiply the second equation to cancel 4y:

6x – 4y = 54
-18x+4y=-138
--------------
-12x=-84
x=7 

If you want to find y you substitute x by either of the equations:

6(7)-4y=54
-4y+42=54
-4y=12
y=-3 

Check:

6(7)-4(-3)=54
42+12=54
54=54
