47 50 | ( | 9 20 | x | + | 2000 | ) | = | x |
| Left side of the equation = | 47 50 | × | 9 20 | x | + | 47 50 | × | 2000 |
| = | 423 1000 | x | + | 1880 |
423 1000 | x | + | 1880 | = | x |
423 1000 | x | − | x | = | - | 1880 |
| - | 577 1000 | x | = | - | 1880 |
| 1880 | = | 577 1000 | x |
577 1000 | x | = | 1880 |
| x | = | 1880 | ÷ | 577 1000 |
| = | 1880 | × | 1000 577 |
| x | = | 1880000 577 |
| x | = | 3258.232236 |
