| ( | i | − | 8 100 | ) | ÷ | ( | - | 1 100 | ) | = | 629 10000 |
| Multiply both sides of the equation by: | ( | - | 1 100 | ) |
| ( | i | − | 8 100 | ) | = | 629 10000 | ( | - | 1 100 | ) |
| i | − | 8 100 | = | 629 10000 | ( | - | 1 100 | ) |
| i | − | 8 100 | = | - | 629 10000 | × | 1 100 |
| i | − | 8 100 | = | - | 629 1000000 |
| i | = | - | 629 1000000 | + | 8 100 |
| i | = | 79371 1000000 |
