| 4 | x | + | 204 | × | 2 | = | 6 | x | × | 205 |
| Left side of the equation = | 4 | x | + | 408 |
| 4 | x | + | 408 | = | 6 | x | × | 205 |
| Right side of the equation = | 1230 | x |
| 4 | x | + | 408 | = | 1230 | x |
| 4 | x | − | 1230 | x | = | - | 408 |
| - | 1226 | x | = | - | 408 |
| 408 | = | 1226 | x |
| 1226 | x | = | 408 |
| x | = | 408 | ÷ | 1226 |
| = | 408 | × | 1 1226 |
| = | 204 | × | 1 613 |
| x | = | 204 613 |
| x | = | 0.33279 |
