Two numbers qhose sum is 58 and whose difference is 16?

Answer 1

21 + 37 = 58

How It's Solved

Let 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.
