Zeph and Henry had a total of 158 marbles at first. After Zeph bought 22 more marbles and Henry gave away 14 marbles, Zeph now has the same number of marbles as Henry. How many marbles did Zeph have at first?

Zeph |
Henry |
Total |
| Before |
1 u - 22 |
1 u + 14 |
158 |
| Change |
+ 22 |
- 14 |
|
| After |
1 u |
1 u |
166 |
Total number of marbles in the end
= 158 + 22 - 14
= 166
2 u = 166
1 u = 166 ÷ 2 = 83
Number of marbles that Zeph had in the end
= 1 u
= 83
Number of marbles that Zeph had at first
= 83 - 22
= 61
Answer(s): 61
