| x | ÷ | ( | 2 | x | − | 12 | ) | + | x | ÷ | 10 | = | 12 5 |
| Multiply both sides of the equation by: | ( | 2 | x | − | 12 | ) |
| x | + | x | ÷ | 10 | × | ( | 2 | x | − | 12 | ) | = | 12 5 | ( | 2 | x | − | 12 | ) |
| x | + | x | ÷ | 10 | × | 2 | x | − | x | ÷ | 10 | × | 12 | = | 12 5 | ( | 2 | x | − | 12 | ) |
| x | + | x | ÷ | 10 | × | 2 | x | − | x | ÷ | 10 | × | 12 | = | 12 5 | × | 2 | x | − | 12 5 | × | 12 |
| x | + | x | × | 1 5 | x | − | x | × | 6 5 | = | 24 5 | x | − | 144 5 |
| - | 1 5 | x | + | x | × | 1 5 | x | = | 24 5 | x | − | 144 5 |
