Xavier had $135 more than Simon at first. If Simon had another $135 at first, both of them would had the same amount of money.
6 u - 140 = 1 u + 140 + 135
6 u - 140 = 1 u + 275
6 u - 1 u = 140 + 275
5 u = 415
1 u = 415 ÷ 5 = 83
Amount that Xavier had at first
= 6 u - 140
= 6 x 83 - 140
= 498 - 140
= $358
Answer(s): $358
