53 50 | x | − | 19 20 | ( | 11000 | − | x | ) | = | 11000 | × | 51 50 |
| Left side of the equation = | 53 50 | x | − | 19 20 | × | 11000 | + | 19 20 | x |
| = | 53 50 | x | − | 10450 | + | 19 20 | x |
| = | 201 100 | x | − | 10450 |
201 100 | x | − | 10450 | = | 11000 | × | 51 50 |
| Right side of the equation = | 11220 |
201 100 | x | − | 10450 | = | 11220 |
201 100 | x | = | 11220 | + | 10450 |
201 100 | x | = | 21670 |
| x | = | 21670 | ÷ | 201 100 |
| = | 21670 | × | 100 201 |
| x | = | 2167000 201 |
| x | = | 10781.094527 |
