    x=16/3

    Step-by-step explanation:

    left part : - 1+3x-8

    right part: 7

    left part = right part

    -1+3x-8=7

    left part + 8 = right part + 8

    -1 + 3x - 8 + 8=7+8

    -1+3x=15

    left part : - 1+3x

    right part : 15

    left part+1=right part+1

    -1+3x+1=15+1

    3x=16

    so

    x=16/3
