    Answer: - 3.5

    Step-by-step explanation:

    y = 4x - 6. Given

    to calculate for x, for y = - 20

    from the given equation,

    y = 4x - 6

    substitute y = - 20

    -20 = 4x - 6

    taking like terms

    -20 + 6 = 4x

    -14 = 4x

    divide both sides by 4

    -14/4 = 4x/4

    x = - 3.5
