| ( | 22 25 | x | ) | − | ( | 1 10 | x | ) | − | ( | 1 10 | x | ) | = | 400 |
| Left side of the equation = | 22 25 | x | − | ( | 1 10 | x | ) | − | ( | 1 10 | x | ) |
| = | 22 25 | x | − | 1 10 | x | − | ( | 1 10 | x | ) |
| = | 39 50 | x | − | ( | 1 10 | x | ) |
| = | 39 50 | x | − | 1 10 | x |
| = | 17 25 | x |
17 25 | x | = | 400 |
| x | = | 400 | ÷ | 17 25 |
| = | 400 | × | 25 17 |
| x | = | 10000 17 |
| x | = | 588.235294 |
