| ( | x | − | 1419 1000 | ) | × | 200 | − | 1 10 | = | 1 |
| Left side of the equation = | x | × | 200 | − | 1419 1000 | × | 200 | − | 1 10 |
| = | x | × | 200 | − | 1419 5 | − | 1 10 |
| = | 200 | x | − | 2839 10 |
| 200 | x | − | 2839 10 | = | 1 |
| 200 | x | = | 1 | + | 2839 10 |
| 200 | x | = | 2849 10 |
| x | = | 2849 10 | ÷ | 200 |
| = | 2849 10 | × | 1 200 |
| x | = | 2849 2000 |
