| 100 | x | = | ( | 100 | − | ( | 100 | x | ) | ) | × | 1 10 |
| Right side of the equation = | 100 | × | 1 10 | − | ( | 100 | x | ) | × | 1 10 |
| = | 10 | − | ( | 100 | x | ) | × | 1 10 |
| = | 10 | − | 100 | x | × | 1 10 |
| = | 10 | − | 10 | x |
| 100 | x | = | 10 | − | 10 | x |
| 100 | x | + | 10 | x | = | 10 |
| 110 | x | = | 10 |
| x | = | 10 | ÷ | 110 |
| = | 10 | × | 1 110 |
| = | 1 | × | 1 11 |
| x | = | 1 11 |
| x | = | 0.090909 |
