49 as many beads as Jean. After Oscar bought another 83 beads, he had 12 less beads than Jean. How many beads did Oscar have at first?

| After |
4 u + 83 |
9 u |
Jean had 12 more beads than Oscar in the end. So, if Oscar had another 12 beads, he would have the same number of beads as Jean.
9 u = 4 u + 83 + 12
9 u - 4 u = 83 + 12
5 u = 95
1 u = 95 ÷ 5 = 19
Number of beads that Oscar had at first
= 4 u
= 4 x 19
= 76
Answer: 76
