    X = 13

    y=16

    Work:

    x+y=29

    x=29-y

    x+2y=45

    29-y+2y=45

    y=45-29

    y=16

    x=29-16

    x=13

    x+y=29

    y=29-x

    x+2y=45

    x+2 (29-x) = 45

    x+58-2x=45

    -1x=-13

    x=13

    y=29-13=16

    x+y = 13+16 = 29

    x+2y = 13 + 2 (16) = 13+32 = 45

    so the numbers are 13 & 16
