This document contains 8 equations with variables. The equations include addition, subtraction, multiplication and division of variables. The goal is to solve for the value of x in each equation.

1. 3x + 5 = 20 5x + 85 = 20
2x - 3 = 27 3x-12 = 270
12 - 5x = 27 12-10x = 212
15 – 4x = 11 15 – 3x = 111
9 + 7x = 23 9 + 2x = 213
19 + 6x = 7 117 + 9x = 81
