| 1 | + | x | = | 10 | ( | 1 | − | x | ) | ( | 1 | − | x | ) |
| Right side of the equation = | 10 | × | 1 | ( | 1 | − | x | ) | − | 10 | x | ( | 1 | − | x | ) |
| = | 10 | ( | 1 | − | x | ) | − | 10 | x | ( | 1 | − | x | ) |
| = | 10 | × | 1 | − | 10 | x | − | 10 | x | ( | 1 | − | x | ) |
| = | 10 | − | 10 | x | − | 10 | x | ( | 1 | − | x | ) |
| = | 10 | − | 10 | x | − | 10 | x | × | 1 | + | 10 | x | x |
| = | 10 | − | 10 | x | − | 10 | x | + | 10 | x | x |
| = | 10 | − | 20 | x | + | 10 | x | x |
| 1 | + | x | = | 10 | − | 20 | x | + | 10 | x | x |
| x1= | 3 5 |
