| x | ÷ | ( | x | + | 35 | ) | × | 100 | = | 0 |
| Multiply both sides of the equation by: | ( | x | + | 35 | ) |
| x | × | 100 | = | 0 |
| x | = | 0 | ÷ | 100 |
| = | 0 | × | 1 100 |
| x | = | 0 |
4 5 | x | ÷ | ( | 4 5 | x | + | 60 | ) | × | 100 | = | 0 |
| Multiply both sides of the equation by: | ( | 4 5 | x | + | 60 | ) |
4 5 | x | × | 100 | = | 0 |
| 80 | x | = | 0 |
| x | = | 0 | ÷ | 80 |
| = | 0 | × | 1 80 |
| x | = | 0 |
