    y = 24

    Step-by-step explanation:

    3x + y = 6

    Solve for y

    Subtract 3x from each side

    3x - 3x + y = 6-3x

    y = 6-3x

    Let x = - 6

    y = 6 - 3 (-6)

    =6+18

    =24

    1. 3x + y = 6

    2. 3 (-6) + y = 6

    3. - 18 + y = 6

    4. + 18 + 18

    5. y = 24

    Therefore, 3 (-6) + (24) = 6

    -18 + 24 = 6
