| 190000000 | = | 2760 | ( | 385 | − | x | ÷ | 2 | ) |
| Right side of the equation = | 2760 | × | 385 | − | 2760 | x | ÷ | 2 |
| = | 1062600 | − | 1380 | x |
| 190000000 | = | 1062600 | − | 1380 | x |
| 1380 | x | = | 1062600 | − | 190000000 |
| 1380 | x | = | - | 188937400 |
| x | = | - | 188937400 | ÷ | 1380 |
| = | - | 188937400 | × | 1 1380 |
| = | - | 9446870 | × | 1 69 |
| x | = | - | 9446870 69 |
