    B. 3x+7=22

    Step-by-step explanation:

    Lets solve each equation alone to find the possible solutions.

    A. 2x+9=15

    Putting like terms together.

    2x=15-9

    2x=6

    x=3

    B. 3x+7=22

    Collecting like terms together:

    3x=22-7

    3x=15

    x=5

    C. 2x-5=17

    2x=17+5

    2x=22

    x=11

    D. 3x-6=15

    3x=15+6

    3x=21

    x=7.

    The only equation that gives x=5 is B. 3x+7 = 22
