| ( | x | x | ) | ÷ | ( | ( | 3 250 | − | x | ) | ( | 1 100 | − | x | ) | ) | = | 9 4 |
| Multiply both sides of the equation by: | ( | ( | 3 250 | − | x | ) | ( | 1 100 | − | x | ) | ) |
| ( | x | x | ) | = | 9 4 | ( | ( | 3 250 | − | x | ) | ( | 1 100 | − | x | ) | ) |
| x | x | = | 9 4 | ( | ( | 3 250 | − | x | ) | ( | 1 100 | − | x | ) | ) |
| x | x | = | 9 4 | ( | 3 250 | − | x | ) | ( | 1 100 | − | x | ) |
| x | x | = | 9 4 | × | 3 250 | ( | 1 100 | − | x | ) | − | 9 4 | x | ( | 1 100 | − | x | ) |
| x | x | = | 27 1000 | ( | 1 100 | − | x | ) | − | 9 4 | x | ( | 1 100 | − | x | ) |
| x | x | = | 27 1000 | × | 1 100 | − | 27 1000 | x | − | 9 4 | x | ( | 1 100 | − | x | ) |
| x | x | = | 27 100000 | − | 27 1000 | x | − | 9 4 | x | ( | 1 100 | − | x | ) |
| x | x | = | 27 100000 | − | 27 1000 | x | − | 9 4 | x | × | 1 100 | + | 9 4 | x | x |
