| ( | 25 | ÷ | 22 | ) | x | + | ( | 50 | ÷ | 11 | ) | = | 0 |
| Left side of the equation = | 25 | ÷ | 22 | × | x | + | ( | 50 | ÷ | 11 | ) |
| = | 25 22 | x | + | ( | 50 | ÷ | 11 | ) |
| = | 25 22 | x | + | 50 | ÷ | 11 |
| = | 25 22 | x | + | 50 11 |
25 22 | x | + | 50 11 | = | 0 |
25 22 | x | = | 0 | − | 50 11 |
25 22 | x | = | - | 50 11 |
| x | = | - | 50 11 | ÷ | 25 22 |
| = | - | 50 11 | × | 22 25 |
| = | - | 2 | × | 2 |
