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
-4 + 7 = 37 - -4 = 11-4 and 7
37 and 45
They are: 29+5+3 = 37
2 and 1 .their sum is 3 .difference is 1
3, 5, 29
-4 + 7 = 37 - -4 = 11-4 and 7
37 + 29 = 66 37 - 29 = 8
16 and 21
37 and 45
That would be 24 and 61, sum: 24+61=85 and 61-24=37
3 + 2 = 5. (sum) 3 - 2 = 1. (difference)
10 and 5
It is: 3 times (37+45) = 246
3, 7 and 37
29, 5 and 3
3 and 9 Difference: 9-3=6 Sum: 9+3=12
They are: 29+5+3 = 37
