| x | + | 963 10 | = | 49 50 | ( | x | ÷ | 9 10 | + | 98 | ) |
| 方程右边 = | 49 50 | x | ÷ | 9 10 | + | 49 50 | × | 98 |
| = | 49 45 | x | + | 2401 25 |
| x | + | 963 10 | = | 49 45 | x | + | 2401 25 |
| x | − | 49 45 | x | = | 2401 25 | − | 963 10 |
| - | 4 45 | x | = | 2401 25 | − | 963 10 |
| - | 4 45 | x | = | - | 13 50 |
13 50 | = | 4 45 | x |
4 45 | x | = | 13 50 |
| x | = | 13 50 | ÷ | 4 45 |
| = | 13 50 | × | 45 4 |
| = | 13 10 | × | 9 4 |
| x | = | 117 40 |
| x | = | 2.925 |
