35 as many beads as Roshel. After Jack bought another 24 beads, he had 12 less beads than Roshel. How many beads did Jack have at first?

3 u + 24 |
5 u |
Roshel had 12 more beads than Jack in the end. So, if Jack had another 12 beads, he would have the same number of beads as Roshel.
5 u = 3 u + 24 + 12
5 u - 3 u = 24 + 12
2 u = 36
1 u = 36 ÷ 2 = 18
Number of beads that Jack had at first
= 3 u
= 3 x 18
= 54
Answer: 54
