    x = - 4, y = 3.

    Step-by-step explanation:

    3x - 4y = - 24 ... (1).

    x + y = - 1 Multiply this equation by - 3:-

    -3x - 3y = 3 ... (2)

    Adding (1) and (2):

    -7y = - 21

    y = 3.

    Substitute y = 3 in equation (1):

    3x - 4 (3) = - 24

    3x = - 24 + 12

    3x = - 12

    x = - 4.

    3x - 28 = - 24

    3x = 4
