    Make an equation:

    L = 4S - 3

    Where 'L' is the amount of DVD's Leah has and 'S' is the aount of DVD's Sonia has.

    Plug in 37 for 'L' and solve for 'S':

    37 = 4S - 3

    Add 3 to both sides:

    40 = 4S

    Divide 4 to both sides:

    S = 10

    So Sonia has 10 DVD's.

    X = sonias dvds

    37 = 4x - 3

    +3 + 3

    40 = 4x

    10 = x

    sonia has 10 dvds
