Since it is asking for the numbers of the SUM of 74, we know its the addition of 2 different numbers.
All we have to do is divide 74 by 2, which is 37. Then, since we know the larger number is 4 more than the small number, you add 2 to 37 and subtract 2 from the other 37.
72/2 =37 + 37
37 + 2 = 39
37 - 2 = 35
39 + 35 = 74
39 - 35 = a difference of 4
So your two numbers are 39 and 35.
