    30x + 20 = 50

    20 + - 20 + 30x = 50 + - 20

    0 + 30x = 50 + - 20 30x = 50 + - 20

    50 + - 20 = 30 30x = 30

    x = 1

    30x - 20 = 50

    use inverse operations to isolate x

    30x - 20 = 50

    + 20 + 20

    30x = 70

    (30x = 70) / 30

    x = 7/3 (this is the simplified term)
