Gerardo Hobbs · Answer 1

x = 11/2 or - 17/2.

Step-by-step explanation:

9 = |2x+3| - 5

9 + 5 = |2x+3|

|2x + 3| = 14

2x + 3 = 14 or 2x + 3 = - 14

x = 11/2 or - 17/2.

Arden · Answer 2

9+5=|2x+3|

14=|2x+3|

2 scenarios:

(1) 2x+3 >=0, equation is now 14=2x+3

11=2x

x=5.5

(2) 2x+3<0, equation is now 14 = - (2x+3)

2x+3+14=0

2x=-17

x=-8.5
