| ( | x | ÷ | ( | 5 | + | 5 | ) | ) | + | ( | 2 | ÷ | 4 | ) | = | 0 |
| x | ÷ | ( | 5 | + | 5 | ) | + | ( | 2 | ÷ | 4 | ) | = | 0 |
| Multiply both sides of the equation by: | ( | 5 | + | 5 | ) |
| x | + | ( | 2 | ÷ | 4 | ) | ( | 5 | + | 5 | ) | = | 0 |
| x | + | 2 | ÷ | 4 | × | ( | 5 | + | 5 | ) | = | 0 |
| x | + | 1 2 | ( | 5 | + | 5 | ) | = | 0 |
| x | + | 1 2 | × | 5 | + | 1 2 | × | 5 | = | 0 |
| x | + | 5 2 | + | 5 2 | = | 0 |
| x | + | 5 | = | 0 |
| x | = | 0 | − | 5 |
| x | = | - | 5 |
