| ( | 3 4 | x | − | 270 | ) | ÷ | 3800 | = | ( | 3 4 | x | − | 425 | ) | ÷ | 2800 |
| Left side of the equation = | 3 4 | x | × | 1 3800 | − | 270 | × | 1 3800 |
| = | 3 15200 | x | − | 27 380 |
3 15200 | x | − | 27 380 | = | ( | 3 4 | x | − | 425 | ) | ÷ | 2800 |
| Right side of the equation = | 3 4 | x | × | 1 2800 | − | 425 | × | 1 2800 |
| = | 3 11200 | x | − | 17 112 |
3 15200 | x | − | 27 380 | = | 3 11200 | x | − | 17 112 |
3 15200 | x | − | 3 11200 | x | = | - | 17 112 | + | 27 380 |
