Question

The sum of two integers is 43 and their difference is 7. Find the integers.

Answer 1

25 and 18

Explanation:

Let's call the first Integer X and the second Y
There has to be a difference of 7 between X and Y so lets say X is the bigger
X - 7 = Y

2x must be 7 more than 43. 7 more than 43 is 50. Therefore X has to be 1/2 of 50.
X = 25 because 25 is 1/2 of 50.

Now we have to find 7 less than 25
25 - 7 = 18.

25 + 18 = 43
Therefore 25 and 18 are the integers
