Oscar had $134 more than Valen at first. If Valen had another $134 at first, both of them would had the same amount of money.
3 u - 122 = 1 u + 122 + 134
3 u - 122 = 1 u + 256
3 u - 1 u = 122 + 256
2 u = 378
1 u = 378 ÷ 2 = 189
Amount that Oscar had at first
= 3 u - 122
= 3 x 189 - 122
= 567 - 122
= $445
Answer(s): $445
