    x=12

    Step-by-step explanation:

    0.75x+12=21

    Subtract 12 from each side

    0.75x+12-12=21-12

    .75x = 9

    Divide each side by. 75

    .75x/.75 = 9/.75

    x = 12

    Subtract 12 from both sides

    0.75x = 21 - 12

    Simplify 21 - 12 to 9

    0.75x = 9

    Divide both sides by 0.75

    x = 9/0.75

    Simplify 9/0.75 to 12

    x = 12
