    x=7

    Step-by-step explanation:

    1) subtract the variable on both sides

    4=3x-8+3-12

    2) get the variable by itself

    -8+3=-5-12 = - 17

    4=3x-17

    +17 + 17

    21=3x

    3) divide the variable with the whole number

    21/3=7

    so ... x=7

    x=7

    Step-by-step explanation:

    4 + 3x = 6x-8 + 3 - 12

    4 + 3x = 6x-17

    -3x - 3x

    4 = 3x - 17

    +17 + 17

    21 = 3x

    divide by 3 on both sides

    7 = x

    switch the side that x is on because teachers like that

    x = 7
