Julian had $138 more than Ken at first. If Ken had another $138 at first, both of them would had the same amount of money.
3 u - 126 = 1 u + 126 + 138
3 u - 126 = 1 u + 264
3 u - 1 u = 126 + 264
2 u = 390
1 u = 390 ÷ 2 = 195
Amount that Julian had at first
= 3 u - 126
= 3 x 195 - 126
= 585 - 126
= $459
Answer(s): $459
