    X + 2y = 3 Solve the Equation

    - 2y - 2y

    x = 3 - 2y

    5x + 3y = 8

    5 (3 - 2y) + 3y = 8 Substitute x

    15 - 10y + 3y = 8 Combine Like Terms

    15 - 7y = 8

    -15 - 15

    -7y = - 7

    Divide 7 from y (Do on both sides)

    y = 1

    x = 3 - 2 (1) Substitute y

    x = 3 - 2

    x = 1

    (X, Y) = (1, 1)
