There was an equal number of green and pink beads in a bag at first. After 18 pink beads were taken out and 30 green beads were added into the bag, there was
17 as many pink beads as green beads. Find the number of pink beads in the bag at first.

Green beads |
Pink beads |
Before |
7 u - 30 |
1 u + 18 |
Change |
+ 30 |
- 18 |
After |
7 u |
1 u |
The number of green and pink beads in the bag is the same at first.
7 u - 30 = 1 u + 18
7 u - 1 u = 18 + 30
6 u = 48
1 u = 48 ÷ 6 = 8
Number of pink beads at first
= 1 u + 18
= 8 + 18
= 26
Answer(s)26
