| ( | 1 | + | x | + | 23 10 | ) | = | ( | 1 | + | x | ) | × | 6 5 | × | 7 5 | × | 5 4 |
| Left side of the equation = | 1 | + | x | + | 23 10 |
| = | 33 10 | + | x |

33 10 | + | x | = | 21 10 | + | 21 10 | x |
| x | − | 21 10 | x | = | 21 10 | − | 33 10 |
| - | 11 10 | x | = | 21 10 | − | 33 10 |
| - | 11 10 | x | = | - | 6 5 |
