| ( | x | − | 315809 5000 | ) | ÷ | ( | x | + | 2 | ) | = | 373 1000 |
| 方程两边同时乘以: | ( | x | + | 2 | ) |
| ( | x | − | 315809 5000 | ) | = | 373 1000 | ( | x | + | 2 | ) |
| x | − | 315809 5000 | = | 373 1000 | ( | x | + | 2 | ) |
| x | − | 315809 5000 | = | 373 1000 | x | + | 373 1000 | × | 2 |
| x | − | 315809 5000 | = | 373 1000 | x | + | 373 500 |
| x | − | 373 1000 | x | = | 373 500 | + | 315809 5000 |
627 1000 | x | = | 373 500 | + | 315809 5000 |
627 1000 | x | = | 319539 5000 |
| x | = | 319539 5000 | ÷ | 627 1000 |
| = | 319539 5000 | × | 1000 627 |
| = | 9683 5 | × | 1 19 |
| x | = | 9683 95 |
| x | = | 101.926316 |
