Answer:

We simplify the equation to the form, which is simple to understand  

5x+15=4x-12

We move all terms containing x to the left and all other terms to the right.  

+5x-4x=-12-15

We simplify left and right side of the equation.  

+1x=-27

then divide both sides of the equation by 1 to get x.  

x=-27
