| x | ÷ | ( | 1345 | + | x | ) | = | 11 200 |
| 方程两边同时乘以: | ( | 1345 | + | x | ) |
| x | = | 11 200 | ( | 1345 | + | x | ) |
| x | = | 11 200 | × | 1345 | + | 11 200 | x |
| x | = | 2959 40 | + | 11 200 | x |
| x | − | 11 200 | x | = | 2959 40 |
189 200 | x | = | 2959 40 |
| x | = | 2959 40 | ÷ | 189 200 |
| = | 2959 40 | × | 200 189 |
| = | 2959 | × | 5 189 |
| x | = | 14795 189 |
| x | = | 78.280423 |
