| 2 | ( | x | − | 180 | ) | = | 3 | ( | x | − | 500 | ) |
| Left side of the equation = | 2 | x | − | 2 | × | 180 |
| = | 2 | x | − | 360 |
| 2 | x | − | 360 | = | 3 | ( | x | − | 500 | ) |
| Right side of the equation = | 3 | x | − | 3 | × | 500 |
| = | 3 | x | − | 1500 |
| 2 | x | − | 360 | = | 3 | x | − | 1500 |
| 2 | x | − | 3 | x | = | - | 1500 | + | 360 |
| - | x | = | - | 1500 | + | 360 |
| - | x | = | - | 1500 | + | 360 |
| - | x | = | - | 1140 |
| 1140 | = | x |
| x | = | 1140 |
