| ( | x | − | 5000 | ) | × | 10 100 | − | 2520 | = | x | − | 45000 |
| Left side of the equation = | x | × | 10 100 | − | 5000 | × | 10 100 | − | 2520 |
| = | x | × | 10 100 | − | 500 | − | 2520 |
| = | 10 100 | x | − | 3020 |
10 100 | x | − | 3020 | = | x | − | 45000 |
10 100 | x | − | x | = | - | 45000 | + | 3020 |
| - | 9 10 | x | = | - | 45000 | + | 3020 |
| - | 9 10 | x | = | - | 41980 |
| 41980 | = | 9 10 | x |
9 10 | x | = | 41980 |
| x | = | 41980 | ÷ | 9 10 |
| = | 41980 | × | 10 9 |
| x | = | 419800 9 |
| x | = | 46644.444444 |
