    7x-9=19

    Add 9 both sides

    7x-9+9=9+19

    7x=28

    Divide both sides by 7

    7x/7=28/7

    Simplify

    X = 4

    To check substitute into original equation.

    7x-9=19

    7 (4) - 9 = 19

    28-9 = 19

    19=19 it checks

    x=4

    19 plus 9 is 28

    28 divide by 7 is 4

    7 times 4 plus 9 is 19
