| 5 | ( | x | − | 740 | ) | = | 4 | ( | x | − | 300 | ) |
| Left side of the equation = | 5 | x | − | 5 | × | 740 |
| = | 5 | x | − | 3700 |
| 5 | x | − | 3700 | = | 4 | ( | x | − | 300 | ) |
| Right side of the equation = | 4 | x | − | 4 | × | 300 |
| = | 4 | x | − | 1200 |
| 5 | x | − | 3700 | = | 4 | x | − | 1200 |
| 5 | x | − | 4 | x | = | - | 1200 | + | 3700 |
| x | = | - | 1200 | + | 3700 |
| x | = | - | 1200 | + | 3700 |
| x | = | 2500 |
