You need to divide when you want to isolate the variable, which in this case is x. To isolate x, you need to get rid of the constant (the number not involving x) on the same side of the equation as x. In this case, you can get rid of -224 by dividing both sides of the equation by 4.
-224/4 = 4x/4
Simplifying:
-56 = x
So x equals -56.
-224= 4x
