  1. Step-by-step explanation:

    x+y = 25. (1)

    XY= 100. (2)

    X = 25-y

    (25-y)y =100

    25y-y^2-100

    y^2-25y+100

    y^2-20y-5y+100

    y(y-20). -5(y-20)

    (y-5). (y-20)

    y =5

    y=20

    X + y = 25

    X + 20 = 25

    X = 25-20

    X =5

    their difference is

    20-5 =15
