| x | ÷ | x | + | 3 | = | x | ÷ | ( | 3 | x | + | 1 | ) |
| Multiply both sides of the equation by: | x | , | ( | 3 | x | + | 1 | ) |
| x | ( | 3 | x | + | 1 | ) | + | 3 | x | ( | 3 | x | + | 1 | ) | = | x | x |
| x | × | 3 | x | + | x | × | 1 | + | 3 | x | ( | 3 | x | + | 1 | ) | = | x | x |
| x | × | 3 | x | + | 1 | x | + | 3 | x | × | 3 | x | + | 3 | x | × | 1 | = | x | x |
| x | × | 3 | x | + | 1 | x | + | 9 | x | x | + | 3 | x | = | x | x |
| x | × | 3 | x | + | 4 | x | + | 9 | x | x | = | x | x |
