29 5 | x | + | 607 25 | = | 63 10 | ( | x | + | 31 10 | ) |
| 方程右边 = | 63 10 | x | + | 63 10 | × | 31 10 |
| = | 63 10 | x | + | 1953 100 |
29 5 | x | + | 607 25 | = | 63 10 | x | + | 1953 100 |
29 5 | x | − | 63 10 | x | = | 1953 100 | − | 607 25 |
| - | 1 2 | x | = | 1953 100 | − | 607 25 |
| - | 1 2 | x | = | - | 19 4 |
19 4 | = | 1 2 | x |
1 2 | x | = | 19 4 |
| x | = | 19 4 | ÷ | 1 2 |
| = | 19 4 | × | 2 |
| = | 19 2 | × | 1 |
| x | = | 19 2 |
| x | = | 9.5 |
