29 as many buttons as Opal. After Asher bought another 83 buttons, he had 15 less buttons than Opal. How many buttons did Asher have at first?

2 u + 83 |
9 u |
Opal had 15 more buttons than Asher in the end. So, if Asher had another 15 buttons, he would have the same number of buttons as Opal.
9 u = 2 u + 83 + 15
9 u - 2 u = 83 + 15
7 u = 98
1 u = 98 ÷ 7 = 14
Number of buttons that Asher had at first
= 2 u
= 2 x 14
= 28
Answer: 28
