| b | ÷ | ( | 345959 500 | + | b | ) | = | 24 | ÷ | 500 |
| 方程两边同时乘以: | ( | 345959 500 | + | b | ) |
| b | = | 24 | ÷ | 500 | × | ( | 345959 500 | + | b | ) |
| b | = | 24 | ÷ | 500 | × | 345959 500 | + | 24 | ÷ | 500 | × | b |
| b | = | 1037877 31250 | + | 6 125 | b |
| b | − | 6 125 | b | = | 1037877 31250 |
119 125 | b | = | 1037877 31250 |
| b | = | 1037877 31250 | ÷ | 119 125 |
| = | 1037877 31250 | × | 125 119 |
| = | 1037877 250 | × | 1 119 |
