| 200 | x | = | 2 | × | 150 | ( | x | − | 2 | ) |
| Right side of the equation = | 300 | ( | x | − | 2 | ) |
| 200 | x | = | 300 | ( | x | − | 2 | ) |
| Right side of the equation = | 300 | x | − | 300 | × | 2 |
| = | 300 | x | − | 600 |
| 200 | x | = | 300 | x | − | 600 |
| 200 | x | − | 300 | x | = | - | 600 |
| - | 100 | x | = | - | 600 |
| 600 | = | 100 | x |
| 100 | x | = | 600 |
| x | = | 600 | ÷ | 100 |
| = | 600 | × | 1 100 |
| = | 6 | × | 1 |
| x | = | 6 |
