Vaidev had $157 more than Elijah at first. If Elijah had another $157 at first, both of them would had the same amount of money.
4 u - 130 = 1 u + 130 + 157
4 u - 130 = 1 u + 287
4 u - 1 u = 130 + 287
3 u = 417
1 u = 417 ÷ 3 = 139
Amount that Vaidev had at first
= 4 u - 130
= 4 x 139 - 130
= 556 - 130
= $426
Answer(s): $426
