    Answer:

    x = his sister’s height = 19 inches

    Step-by-step explanation:

    Let

    x = his sister’s height

    Jahlil’s height is given by the equation:

    4x – 6 = 70

    4x = 70 + 6

    4x = 76

    x = 76/4

    x = 19 inches

    x = his sister’s height = 19 inches

    Check:

    4x – 6 = 70

    4(19) – 6 = 70

    76 – 6 = 70

    70 = 70
