1. 2x = 462. M – 5 = 2333. 6 + j = 58

Chapter 3.1 Solving two step equations

Using subtraction and division to solve: Using addition and multiplication to solve:

3x + 7 = -5 solve for x x – 3 = 1 solve for x

3x + 7 = -5 x – 3 = 1 -7 -7 3x = -12 3 3 x = -4 x = 8

Steps to take for solving:1. Draw in your balance line.2. Do the inverse operation for
