Pomegranates |
Tomatoes |
| Before |
2 u |
4 u - 36 |
| Change |
- 1 u |
+ 36 |
| After |
1 u |
4 u |
The number of tomatoes and pomegranates at first is the same.
4 u - 36 = 2 u
4 u - 2 u = 36
2 u = 36
1 u = 36 ÷ 2 = 18
Number of pomegranates that she had at first
= 2 u
= 2 x 18
= 36
Answer(s): 36
