I assume you mean 3x - 3 = 10 In algebra there is no "correct" first step to solving for x as long as you follow math rules, however the easiest first step is to add 3 to both sides (REMEMBER THAT WHATEVER YOU DO ON ONE SIDE OF THE EQUATION YOU HAVE TO DO TO THE OTHER) Therefore: 3x - 3 = 10 3x - 3 + 3 = 10 + 3 3x = 13 Notice that when we do this we have fewer terms to deal with on the left hand side. See if you can finish it off.
