Question

Solve: |2x+3|-6=11
A) 7 or -10
B) -7 or -10
C) -7 or 10
D) 7 or 10

Answer 1

|2x+3| - 6  =11

|2x+3| = 11+6 = 17

2x+3 = 17 or 2x+3 = -17
2x = 17-3, or 2x = -17-3

2x = 14 or 2x = -20
x = 7 or x = -10

7 or -10

Answer 2

Answer is A, as (2x+3) can either be +17 or -17, so solve for them.
