There was an equal number of brown and pink balls in a bag at first. After 14 pink balls were taken out and 34 brown balls were added into the bag, there was
15 as many pink balls as brown balls. Find the number of pink balls in the bag at first.

Brown balls |
Pink balls |
Before |
5 u - 34 |
1 u + 14 |
Change |
+ 34 |
- 14 |
After |
5 u |
1 u |
The number of brown and pink balls in the bag is the same at first.
5 u - 34 = 1 u + 14
5 u - 1 u = 14 + 34
4 u = 48
1 u = 48 ÷ 4 = 12
Number of pink balls at first
= 1 u + 14
= 12 + 14
= 26
Answer(s)26
