    x = - 4 and y = 27/6

    Step-by-step explanation:

    - (8x + 6y = - 5) which converts to - 8x - 6y = 5

    10x + 6y = - 13

    simplify from there

    -8x + 10x = 2x; - 6y + 6y = 0; 5 - 13 = - 8

    soo, now you have

    2x = - 8

    x = - 4

    then, plug in to find y

    8 (-4) + 6y = - 5

    -32 + 6y = - 5 add 32 on both sides

    6y = 27 divide both sides by 6

    y = 27/6 or 4.5
