| ( | 1918 | − | x | ) | ÷ | x | = | 2503 100000 |
| Multiply both sides of the equation by: | x |
| ( | 1918 | − | x | ) | = | 2503 100000 | x |
| 1918 | − | x | = | 2503 100000 | x |
| - | x | − | 2503 100000 | x | = | - | 1918 |
| - | 102503 100000 | x | = | - | 1918 |
| 1918 | = | 102503 100000 | x |
102503 100000 | x | = | 1918 |
| x | = | 1918 | ÷ | 102503 100000 |
| = | 1918 | × | 100000 102503 |
