| 1350 | + | X | − | ( | 1350 | + | X | ) | × | 9 2500 | = | 5049 2 |
| Left side of the equation = | 1350 | + | X | − | 1350 | × | 9 2500 | − | X | × | 9 2500 |
| = | 1350 | + | X | − | 243 50 | − | X | × | 9 2500 |
| = | 67257 50 | + | 2491 2500 | X |
67257 50 | + | 2491 2500 | X | = | 5049 2 |
2491 2500 | X | = | 5049 2 | − | 67257 50 |
2491 2500 | X | = | 29484 25 |
| X | = | 29484 25 | ÷ | 2491 2500 |
| = | 29484 25 | × | 2500 2491 |
| = | 29484 | × | 100 2491 |
| X | = | 2948400 2491 |
| X | = | 1183.621036 |
