Elijah had
25 as many stamps as Joelle. After Elijah bought another 22 stamps, he had 17 less stamps than Joelle. How many stamps did Elijah have at first?

Joelle had 17 more stamps than Elijah in the end. So, if Elijah had another 17 stamps, he would have the same number of stamps as Joelle.
5 u = 2 u + 22 + 17
5 u - 2 u = 22 + 17
3 u = 39
1 u = 39 ÷ 3 = 13
Number of stamps that Elijah had at first
= 2 u
= 2 x 13
= 26
Answer: 26
