    Answer:

    x = 800 and y = 330

    Step-by-step explanation:

    Let two numbers be x and y.

    Sum of two numbers is 1130.

    Their difference is 470.

    So,

    x+y=1130 …(1)

    x-y = 470 …(2)

    Add equation (1) and (2).

    x+y+x-y = 1130+470

    2x = 1600

    x = 800

    Put the value of x in equation (1)

    800+y=1130

    y = 1130-800

    y = 330

    So, the smallest number is 330 and the largest number is 800.
