    x = 8, y = 4 (8, 4) solution

    Step-by-step explanation:

    Negative 5 x minus 12 y = negative 8. 5 x + 2 y = 48.

    convert to algebra.

    -5x - 12y = - 8;

    5x + 2y = 48

    solve. if we add these equations we get:

    -5x + 5x - 12y + 2y = - 8 + 48

    -10y = 40

    y = 4

    find x.

    5x + 2*4 = 48

    5x + 8 = 48

    5x = 40

    x = 8
