    -8 < x < 13

    Step-by-step explanation:

    |2x-5|<21

    The absolute value has 2 solutions, one positive and one negative. When we take the negative solution, we have to flip the inequality.

    2x-5 - 21

    Add 5 to each side

    2x-5+5 - 21+5

    2x - 16

    Divide by 2

    2x/2 - 16/2

    x - 8

    -8 < x < 13
