    x = 4

    Step-by-step explanation:

    Subtract 8x from both sides

    13x+7-8x=8x+27-8x

    5x+7=27

    Subtract 7 from both sides

    5x+7-7=27-7

    5x=20

    Divide both sides by 5

    5x/5 = 20/5

    x = 4

    x = 4

    Step-by-step explanation:

    Isolate the x:

    13x + 7 = 8x + 27

    subtract 7 from both sides:

    13x = 8x + 20

    subtract 8x from both sides:

    5x = 20

    divide both sides by 5:

    x = 4
