| 22000 | + | 9000 | + | 4400 | + | 3 20 | x | + | 2 25 | x | = | x |
| Left side of the equation = | 35400 | + | 23 100 | x |
| 35400 | + | 23 100 | x | = | x |
23 100 | x | − | x | = | - | 35400 |
| - | 77 100 | x | = | - | 35400 |
| 35400 | = | 77 100 | x |
77 100 | x | = | 35400 |
| x | = | 35400 | ÷ | 77 100 |
| = | 35400 | × | 100 77 |
| x | = | 3540000 77 |
| x | = | 45974.025974 |
