| 5 | ÷ | 6 | × | x | + | 40 | = | 10 | ÷ | 11 | × | x |
| Left side of the equation = | 5 6 | x | + | 40 |
5 6 | x | + | 40 | = | 10 | ÷ | 11 | × | x |
| Right side of the equation = | 10 11 | x |
5 6 | x | + | 40 | = | 10 11 | x |
5 6 | x | − | 10 11 | x | = | - | 40 |
| - | 5 66 | x | = | - | 40 |
| 40 | = | 5 66 | x |
5 66 | x | = | 40 |
| x | = | 40 | ÷ | 5 66 |
| = | 40 | × | 66 5 |
| = | 8 | × | 66 |
| x | = | 528 |
