Harry 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 - 120 = 1 u + 120 + 126
3 u - 120 = 1 u + 246
3 u - 1 u = 120 + 246
2 u = 366
1 u = 366 ÷ 2 = 183
Amount that Harry had at first
= 3 u - 120
= 3 x 183 - 120
= 549 - 120
= $429
Answer(s): $429
