53 50 | x | + | 19 20 | ( | 11000 | − | x | ) | = | 11000 | × | 19 20 |
| Left side of the equation = | 53 50 | x | + | 19 20 | × | 11000 | − | 19 20 | x |
| = | 53 50 | x | + | 10450 | − | 19 20 | x |
| = | 11 100 | x | + | 10450 |
11 100 | x | + | 10450 | = | 11000 | × | 19 20 |
| Right side of the equation = | 10450 |
11 100 | x | + | 10450 | = | 10450 |
11 100 | x | = | 10450 | − | 10450 |
11 100 | x | = | 0 |
| x | = | 0 | ÷ | 11 100 |
| = | 0 | × | 100 11 |
| x | = | 0 |
