| 0 | = | 1000 | x | − | 1000 | x | × | 1000 | + | 600000 |
| Right side of the equation = | 1000 | x | − | 1000000 | x | + | 600000 |
| = | - | 999000 | x | + | 600000 |
| 0 | = | - | 999000 | x | + | 600000 |
| 999000 | x | = | 600000 | − | 0 |
| 999000 | x | = | 600000 |
| x | = | 600000 | ÷ | 999000 |
| = | 600000 | × | 1 999000 |
| = | 200 | × | 1 333 |
| x | = | 200 333 |
| x | = | 0.600601 |
