| ( | 289 2 | − | x | ) | ÷ | ( | 12 5 | x | + | 78 | ) | = | 93 100 |
| 方程两边同时乘以: | ( | 12 5 | x | + | 78 | ) |
| ( | 289 2 | − | x | ) | = | 93 100 | ( | 12 5 | x | + | 78 | ) |
289 2 | − | x | = | 93 100 | ( | 12 5 | x | + | 78 | ) |
289 2 | − | x | = | 93 100 | × | 12 5 | x | + | 93 100 | × | 78 |
289 2 | − | x | = | 279 125 | x | + | 3627 50 |
| - | x | − | 279 125 | x | = | 3627 50 | − | 289 2 |
| - | 404 125 | x | = | 3627 50 | − | 289 2 |
| - | 404 125 | x | = | - | 1799 25 |
1799 25 | = | 404 125 | x |
404 125 | x | = | 1799 25 |
| x | = | 1799 25 | ÷ | 404 125 |
| = | 1799 25 | × | 125 404 |
| = | 1799 | × | 5 404 |
