What is the sum of 37 and a difference of 3?

Answer 1

If the question is, "What two numbers sum to 37 and have a difference of 3?"

Then the answer is 20 and 17

To solve the problem, call the two numbers a and b.

Then a + b = 37 therefore b = 37 - a.

And a - b = 3 : substitute the value (shown above) for b in this equation.

a - (37 - a) = 3 : 2a - 37 = 3 : 2a = 3 + 37 = 40 : a = 20

As a + b = 37 then 20 + b = 37 : b = 37 - 20 = 17
