7x+6=4x+27 The first thing you need to do is get the unknowns, in this case x, to one side and the knowns to the other.

So we subtract 4x from both sides and subtract 6 from both sides

7x+6-4x-6=4x+27-4x-6 or

7x-4x+6-6=4x-4x+26-6 now solve what we can to simplify and we end up with

3x=21 divide each side by 3

3x/3=21/3 simplify and we end with

x=7
