| X | + | 5 4 | ( | 1 10 | − | X | ) | = | 47 400 |
| Left side of the equation = | X | + | 5 4 | × | 1 10 | − | 5 4 | X |
| = | X | + | 1 8 | − | 5 4 | X |
| = | - | 1 4 | X | + | 1 8 |
| - | 1 4 | X | + | 1 8 | = | 47 400 |
| - | 1 4 | X | = | 47 400 | − | 1 8 |
| - | 1 4 | X | = | - | 3 400 |
3 400 | = | 1 4 | X |
1 4 | X | = | 3 400 |
| X | = | 3 400 | ÷ | 1 4 |
| = | 3 400 | × | 4 |
| = | 3 100 | × | 1 |
| X | = | 3 100 |
| X | = | 0.03 |
