47 50 | ( | 9 20 | x | + | 450 | ) | = | x |
| Left side of the equation = | 47 50 | × | 9 20 | x | + | 47 50 | × | 450 |
| = | 423 1000 | x | + | 423 |
423 1000 | x | + | 423 | = | x |
423 1000 | x | − | x | = | - | 423 |
| - | 577 1000 | x | = | - | 423 |
| 423 | = | 577 1000 | x |
577 1000 | x | = | 423 |
| x | = | 423 | ÷ | 577 1000 |
| = | 423 | × | 1000 577 |
| x | = | 423000 577 |
| x | = | 733.102253 |
