| 5 | ÷ | 7 | × | ( | x | + | 39 | ) | = | 7 | ÷ | 11 | + | 39 |
| Left side of the equation = | 5 7 | ( | x | + | 39 | ) |
5 7 | ( | x | + | 39 | ) | = | 7 | ÷ | 11 | + | 39 |
| Left side of the equation = | 5 7 | x | + | 5 7 | × | 39 |
| = | 5 7 | x | + | 195 7 |
5 7 | x | + | 195 7 | = | 7 | ÷ | 11 | + | 39 |
| Right side of the equation = | 7 11 | + | 39 |
| = | 436 11 |
5 7 | x | + | 195 7 | = | 436 11 |
5 7 | x | = | 436 11 | − | 195 7 |
5 7 | x | = | 907 77 |
| x | = | 907 77 | ÷ | 5 7 |
| = | 907 77 | × | 7 5 |
| = | 907 11 | × | 1 5 |
| x | = | 907 55 |
| x | = | 16.490909 |
