Glen had $146 more than Ryan at first. If Ryan had another $146 at first, both of them would had the same amount of money.
3 u - 123 = 1 u + 123 + 146
3 u - 123 = 1 u + 269
3 u - 1 u = 123 + 269
2 u = 392
1 u = 392 ÷ 2 = 196
Amount that Glen had at first
= 3 u - 123
= 3 x 196 - 123
= 588 - 123
= $465
Answer(s): $465
