    3x+33y = - 420

    x+140 = - 11y

    Step-by-step explanation:

    x = - 11y-140

    y + 7x=23

    7x=23-y

    x=23/7 - y/7

    y+11x=140

    11x=140-y

    x=140/11 - y/11

    2x-22y=-140

    2x=-140+22y

    x=-140/2+22y/2

    x=-70+11y

    3x+33y=-420

    3x=-420-33y

    x=-420/3 - 33y/3

    =-140-11y

    x=-140-11y

    x+140=-11y

    x=-11y-140
