| ( | 10 | − | x | ) | × | 8 5 | ÷ | ( | ( | 10 | − | x | ) | × | 8 5 | + | 55 | ) | = | x | × | 1 2 | ÷ | 16 |
| Multiply both sides of the equation by: | ( | ( | 10 | − | x | ) | × | 8 5 | + | 55 | ) |
| ( | 10 | − | x | ) | × | 8 5 | = | x | × | 1 2 | ÷ | 16 | × | ( | ( | 10 | − | x | ) | × | 8 5 | + | 55 | ) |
| 10 | × | 8 5 | − | x | × | 8 5 | = | x | × | 1 2 | ÷ | 16 | × | ( | ( | 10 | − | x | ) | × | 8 5 | + | 55 | ) |
| 10 | × | 8 5 | − | x | × | 8 5 | = | x | × | 1 2 | ÷ | 16 | × | ( | 10 | − | x | ) | × | 8 5 | + | x | × | 1 2 | ÷ | 16 | × | 55 |
| 16 | − | x | × | 8 5 | = | x | × | 1 20 | ( | 10 | − | x | ) | + | x | × | 55 32 |
| 16 | − | 8 5 | x | = | x | × | 1 20 | × | 10 | − | x | × | 1 20 | x | + | 55 32 | x |
| 16 | − | 8 5 | x | = | x | × | 1 2 | − | x | × | 1 20 | x | + | 55 32 | x |
| 16 | − | 8 5 | x | = | 71 32 | x | − | x | × | 1 20 | x |
