# Chapter 1 - Equations and Inequalities - Exercise Set 1.7: 91

#### Answer

$x\lt\frac{-75}{14},x\gt\frac{87}{14}$

#### Work Step by Step

Since we are simplifying an absolute value, first solve for the original inequality, and then flip the sign and make the opposite side negative in the second inequality. $12\lt|-2x+\frac{6}{7}|+\frac{3}{7}$ $|-2x+\frac{6}{7}|\gt\frac{81}{7}$ $-2x+\frac{6}{7}\gt\frac{81}{7}$ $-2x\gt\frac{75}{7}$ $x\lt\frac{-75}{14}$ $-2x+\frac{6}{7}\lt\frac{-81}{7}$ $-2x\lt\frac{-87}{7}$ $x\gt\frac{87}{14}$ $x\lt\frac{-75}{14},x\gt\frac{87}{14}$
