1819 5 | = | ( | 12 | − | x | ) | × | 329 10 | + | 99 5 | x |
| 方程右边 = | 12 | × | 329 10 | − | x | × | 329 10 | + | 99 5 | x |
| = | 1974 5 | − | x | × | 329 10 | + | 99 5 | x |
| = | 1974 5 | − | 131 10 | x |
1819 5 | = | 1974 5 | − | 131 10 | x |
131 10 | x | = | 1974 5 | − | 1819 5 |
131 10 | x | = | 31 |
| x | = | 31 | ÷ | 131 10 |
| = | 31 | × | 10 131 |
| x | = | 310 131 |
| x | = | 2.366412 |
