RE: Problem: The sum of two numbers is 206. If the larger number is 42 more than the smaller, what are the numbers?

Alternatively and easier to calculate in your head. Divide the number by 2 = 103 and then take half of the diff away ie 21 = 82 to get one of the numbers and add half of the difference to the 103 to get the other number ie 21 + 103 = 124
