| ( | X | + | 500 | ÷ | 12 | ) | × | 96 | + | 289 | X | + | ( | X | − | 300 | ÷ | 12 | ) | × | 48 | = | 383025 |
| Left side of the equation = | X | × | 96 | + | 500 | ÷ | 12 | × | 96 | + | 289 | X | + | ( | X | − | 300 | ÷ | 12 | ) | × | 48 |
| = | X | × | 96 | + | 4000 | + | 289 | X | + | ( | X | − | 300 | ÷ | 12 | ) | × | 48 |
| = | 385 | X | + | 4000 | + | ( | X | − | 300 | ÷ | 12 | ) | × | 48 |
| = | 385 | X | + | 4000 | + | X | × | 48 | − | 300 | ÷ | 12 | × | 48 |
| = | 385 | X | + | 4000 | + | X | × | 48 | − | 1200 |
| = | 433 | X | + | 2800 |
| 433 | X | + | 2800 | = | 383025 |
| 433 | X | = | 383025 | − | 2800 |
| 433 | X | = | 380225 |
| X | = | 380225 | ÷ | 433 |
| = | 380225 | × | 1 433 |
| X | = | 380225 433 |
| X | = | 878.117783 |
