Question

What is the solution set for |-2x + 16| - 9 = -3

A. x = -5 and x = -11
B. x = 5 and x = 11
C. x = -5 and x = 11
D. x = 5 and x = -11

Answer 1

First, isolate the abs value expression on one side, like this
|-2x + 16| - 9 = -3
+9 +9
|-2x + 16| = 6
Now, the stuff inside the abs value has to = 6 or = -6
