    1st; Let x = small number. Then from the first sentence, 4x = large number.

    2nd; Complete as the two quantities to be found are assigned variables.

    3rd; The second sentence states conditions placed on the quantities: "their sum is 45."

    x + 4x = 45. Step 3: Solve x + 4x = 45. 5x = 45 x = 9 (small number) 4x = 36 (large number) The solution set to this number problem is {9, 36}.
