Answer:

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

Answer:

x = 11/2 or -17/2.

Step-by-step explanation:

9 + 5 =  |2x+3|

|2x + 3| = 14

2x + 3 = 14  or 2x + 3 = -14

x = 11/2 or -17/2.
