| y | − | 2 | ( | y | ÷ | 101 100 | × | 1 100 | ) | − | ( | y | ÷ | 101 100 | × | 1 100 | × | 7 200 | ) | = | 10000 |
| Left side of the equation = | y | − | 2 | y | ÷ | 101 100 | × | 1 100 | − | ( | y | ÷ | 101 100 | × | 1 100 | × | 7 200 | ) |
| = | y | − | 2 101 | y | − | ( | y | ÷ | 101 100 | × | 1 100 | × | 7 200 | ) |
| = | 99 101 | y | − | ( | y | ÷ | 101 100 | × | 1 100 | × | 7 200 | ) |
| = | 99 101 | y | − | y | ÷ | 101 100 | × | 1 100 | × | 7 200 |
| = | 99 101 | y | − | y | × | 7 20200 |
| = | 19793 20200 | y |
19793 20200 | y | = | 10000 |
| y | = | 10000 | ÷ | 19793 20200 |
| = | 10000 | × | 20200 19793 |
| y | = | 202000000 19793 |
| y | = | 10205.628252 |
