x-y=-4 -----> Get the one of the variables by themselves
x=-4+y -----> All i did was adding the y to the the other side to get x by itself
Now all you do is to substitute the in the equation into the other equation
x=-4+y --------------> 6(-4+y)-4y=-12
Then solve
Now since you have your y now all you need to do is to do the same thing
Substitute the y in for the other equation
Then there you go
