| ( | 2950 | + | 30 | x | ) | ÷ | ( | 29 | + | x | ) | = | 30 |
| Multiply both sides of the equation by: | ( | 29 | + | x | ) |
| ( | 2950 | + | 30 | x | ) | = | 30 | ( | 29 | + | x | ) |
| 2950 | + | 30 | x | = | 30 | ( | 29 | + | x | ) |
| 2950 | + | 30 | x | = | 30 | × | 29 | + | 30 | x |
| 2950 | + | 30 | x | = | 870 | + | 30 | x |
| 30 | x | − | 30 | x | = | 870 | − | 2950 |
| 0 | x | = | 870 | − | 2950 |
| 0 | x | = | - | 2080 |
