    7.

    Step-by-step explanation:

    (-6x14) + (6y) = -42

    (-84) + (6y) = -42

    (-84) + (6y) = -42

    +84 + 84

    6y=42

    42/6=7

    Y=7.

    Y = 7

    -6x + 6y = - 42

    If x = 14, y will be:

    -6x + 6y = - 42

    -6 (14) + 6y = - 42

    -84 + 6y = - 42

    6y = - 42 + 84

    y = 42/6

    y = 7
