| ( | X | − | 3417194113 100 | ) | ÷ | X | = | 13 200 |
| 方程两边同时乘以: | X |
| ( | X | − | 3417194113 100 | ) | = | 13 200 | X |
| X | − | 3417194113 100 | = | 13 200 | X |
| X | − | 13 200 | X | = | 3417194113 100 |
187 200 | X | = | 3417194113 100 |
| X | = | 3417194113 100 | ÷ | 187 200 |
| = | 3417194113 100 | × | 200 187 |
