Chapter 2 - Section 2.6 - Absolute Value Equations - Exercise Set - Page 100: 51

The solution set is $\{ \}$.

$|6+2x| = -|-7|$ We can write it as $|6+2x| = -7$ because $|-7| = 7$ $|6+2x| = -7$ The absolute value of a number is always positive. So this equation has no solution. Solution set is $\{ \}$.
