1 100 | ( | 5000000 | + | x | ) | = | 110000 | + | 3 500 | x |
| Left side of the equation = | 1 100 | × | 5000000 | + | 1 100 | x |
| = | 50000 | + | 1 100 | x |
| 50000 | + | 1 100 | x | = | 110000 | + | 3 500 | x |
1 100 | x | − | 3 500 | x | = | 110000 | − | 50000 |
1 250 | x | = | 110000 | − | 50000 |
1 250 | x | = | 60000 |
| x | = | 60000 | ÷ | 1 250 |
| = | 60000 | × | 250 |
| x | = | 15000000 |
