After |
7 u - 35 |
9 u |
Eva had 71 more buttons than Brandon in the end. So, if Brandon had another 71 buttons, he would have the same number of buttons as Eva.
9 u = 7 u - 35 + 71
9 u - 7 u = 71 - 35
2 u = 36
1 u = 36 ÷ 2 = 18
Number of buttons that Eva had at first
= 9 u
= 9 x 18
= 162
Answer: 162
