| 0 | = | 1200 | x | − | 9 50 | x | − | 800 | x | − | 2200 |
| Right side of the equation = | 19991 50 | x | − | 2200 |
| 0 | = | 19991 50 | x | − | 2200 |
| - | 19991 50 | x | = | - | 2200 | − | 0 |
| - | 19991 50 | x | = | - | 2200 |
| 2200 | = | 19991 50 | x |
19991 50 | x | = | 2200 |
| x | = | 2200 | ÷ | 19991 50 |
| = | 2200 | × | 50 19991 |
| x | = | 110000 19991 |
