| 方程两边同时乘以: | ( | 345959 500 | + | b | ) |
| b | = | 324 | ÷ | 500 | × | ( | 345959 500 | + | b | ) |
| b | = | 324 | ÷ | 500 | × | 345959 500 | + | 324 | ÷ | 500 | × | b |
| b | = | 28022679 62500 | + | 81 125 | b |
| b | − | 81 125 | b | = | 28022679 62500 |
44 125 | b | = | 28022679 62500 |
| b | = | 28022679 62500 | ÷ | 44 125 |
