What is the solution for the equation? 3x + 7 = 11x + 15

The first step to solving multi-step equations is to get rid of any parentheses and combine any like terms on either side of the equal sign. In this problem, there are not any parentheses or like terms so you get to skip that step! 3x + 7 = 11x + 15 -3x -3x ________________ 7 = 8x + 15 -15 -15 _________________ -8 = 8x ___ __ 8 8 -1 = x
