| ( | 5213 10 | − | y | ) | ÷ | y | = | 77 10 |
| Multiply both sides of the equation by: | y |
| ( | 5213 10 | − | y | ) | = | 77 10 | y |
5213 10 | − | y | = | 77 10 | y |
| - | y | − | 77 10 | y | = | - | 5213 10 |
| - | 87 10 | y | = | - | 5213 10 |
5213 10 | = | 87 10 | y |
87 10 | y | = | 5213 10 |
| y | = | 5213 10 | ÷ | 87 10 |
| = | 5213 10 | × | 10 87 |
| = | 5213 | × | 1 87 |
| y | = | 5213 87 |
| y | = | 59.91954 |
