Chapter 2 - Section 2.6 - Absolute Value Equations - Exercise Set: 67

Answer

Solution set is NULL.

Work Step by Step

$|\frac{8c-7}{3}| = -|-5|$ Absolute value of $|a| =-a$ if 'a' is a negative number. So, $|-5|= -(-5) = 5$. We can write the given statement as $|\frac{8c-7}{3}| = -5$ The absolute value of a number can not be negative. Therefore, the given equation has no solution. The solution set is NULL.
