    9. 9&16

    10. 31&45

    Step-by-step explanation:

    9. L-W=7

    2L+2W=50 (system of equations)

    L=W+7

    2L=-2W+50

    L=-W+25

    -W+25=W+7

    -2W=-18

    W=9

    L=16

    10. x=larger number y=smaller number

    x+y=76

    x=y+14

    x=-y+76

    y+14=-y+76

    2y=62

    y=31

    x=45
