21 + 37 = 58
How It's SolvedLet x represent one of the numbers and x - 16 represent the other. Set up the equation and solve:
x + x - 16 = 58 (then simplify)
2x - 16 = 58 (then add 16 to eaxh side to separate the unknown number)
2x = 74 (then divide by 2 to find the value of x)
x = 37 (this is one of the numbers)
Subtract 16 to find the other number:
37 - 16 = 21
The two numbers are 21 and 37.
I know this is a long way to give the same answer as above, but the gist of the lesson is to learn how to solve such problems.
