    1. 3x + 10 = 40

    3x = 40 – 10

    3x = 30

    x = 30/3

    x = 10


    2. x/3 + 7 = 10<div>

    x/3 = 10 – 7

    x/3 = 3

    x = 3*3

    x = 9


    3. x + y + z = 20

    x = 8, z = 3y (given)

    so, 8 + y + 3y = 20

    4y = 20 – 8 = 12

    y = 12/4

    y = 3


    4. 7x – 8 = 6

    7x = 6 + 8 = 14

    x = 14/7

    x = 2

    </div>
