Brandon had $126 more than Bryan at first. If Bryan had another $126 at first, both of them would had the same amount of money.
3 u - 132 = 1 u + 132 + 126
3 u - 132 = 1 u + 258
3 u - 1 u = 132 + 258
2 u = 390
1 u = 390 ÷ 2 = 195
Amount that Brandon had at first
= 3 u - 132
= 3 x 195 - 132
= 585 - 132
= $453
Answer(s): $453
