    One number is 561

    The other number is 23.6854

    Step-by-step explanation:

    x = y^2 One number = the square of another

    x + y^2 = 1122 The sum of the two numbers is 1122

    Substitute y^2 in for x on the second equation.

    y^2 + y^2 = 1122 Combine like terms on the left

    2y^2 = 1122 Divide by 2

    y^2 = 1122/2

    y^2 = 561 Take the square root of both sides.

    y = 23.6854

    x = y^2

    x = 561

    y^2 = 561
