    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

    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.
