| ( | x | − | 150 | ) | ÷ | 3300 | = | ( | x | − | 525 2 | ) | ÷ | 3000 |
| Left side of the equation = | x | × | 1 3300 | − | 150 | × | 1 3300 |
| = | x | × | 1 3300 | − | 1 22 |
1 3300 | x | − | 1 22 | = | ( | x | − | 525 2 | ) | ÷ | 3000 |
| Right side of the equation = | x | × | 1 3000 | − | 525 2 | × | 1 3000 |
| = | x | × | 1 3000 | − | 7 80 |
1 3300 | x | − | 1 22 | = | 1 3000 | x | − | 7 80 |
1 3300 | x | − | 1 3000 | x | = | - | 7 80 | + | 1 22 |
| - | 1 33000 | x | = | - | 7 80 | + | 1 22 |
| - | 1 33000 | x | = | - | 37 880 |
37 880 | = | 1 33000 | x |
1 33000 | x | = | 37 880 |
| x | = | 37 880 | ÷ | 1 33000 |
| = | 37 880 | × | 33000 |
| = | 37 2 | × | 75 |
| x | = | 2775 2 |
