| ( | x | − | 36 5 | ) | × | 149 100 | = | 19 2 |
| 方程左边 = | x | × | 149 100 | − | 36 5 | × | 149 100 |
| = | x | × | 149 100 | − | 1341 125 |
149 100 | x | − | 1341 125 | = | 19 2 |
149 100 | x | = | 19 2 | + | 1341 125 |
149 100 | x | = | 5057 250 |
| x | = | 5057 250 | ÷ | 149 100 |
| = | 5057 250 | × | 100 149 |
| = | 5057 5 | × | 2 149 |
