| ( | 2911 5 | − | y | ) | ÷ | y | = | 71 1000 |
| Multiply both sides of the equation by: | y |
| ( | 2911 5 | − | y | ) | = | 71 1000 | y |
2911 5 | − | y | = | 71 1000 | y |
| - | y | − | 71 1000 | y | = | - | 2911 5 |
| - | 1071 1000 | y | = | - | 2911 5 |
2911 5 | = | 1071 1000 | y |
1071 1000 | y | = | 2911 5 |
| y | = | 2911 5 | ÷ | 1071 1000 |
| = | 2911 5 | × | 1000 1071 |
| = | 2911 | × | 200 1071 |
| y | = | 582200 1071 |
