| ( | 2 | − | 1 10 | ) | x | + | ( | - | 2 | − | 1 10 | ) | ( | 1 | − | x | ) | = | 0 |
| Left side of the equation = | 2 | x | − | 1 10 | x | + | ( | - | 2 | − | 1 10 | ) | ( | 1 | − | x | ) |
| = | 19 10 | x | + | ( | - | 2 | − | 1 10 | ) | ( | 1 | − | x | ) |
| = | 19 10 | x | − | 2 | ( | 1 | − | x | ) | − | 1 10 | ( | 1 | − | x | ) |
| = | 19 10 | x | − | 2 | × | 1 | + | 2 | x | − | 1 10 | ( | 1 | − | x | ) |
| = | 19 10 | x | − | 2 | + | 2 | x | − | 1 10 | ( | 1 | − | x | ) |
| = | 39 10 | x | − | 2 | − | 1 10 | ( | 1 | − | x | ) |
| = | 39 10 | x | − | 2 | − | 1 10 | × | 1 | + | 1 10 | x |
| = | 39 10 | x | − | 2 | − | 1 10 | + | 1 10 | x |
| = | 4 | x | − | 21 10 |
| 4 | x | − | 21 10 | = | 0 |
| 4 | x | = | 0 | + | 21 10 |
| 4 | x | = | 21 10 |
| x | = | 21 10 | ÷ | 4 |
| = | 21 10 | × | 1 4 |
| x | = | 21 40 |
| x | = | 0.525 |
