67 1000 | ( | 153157 1000 | − | y | ) | + | 57 1000 | y | = | 5966 625 |
| Left side of the equation = | 67 1000 | × | 153157 1000 | − | 67 1000 | y | + | 57 1000 | y |
| = | 10261519 1000000 | − | 67 1000 | y | + | 57 1000 | y |
| = | 10261519 1000000 | − | 1 100 | y |
10261519 1000000 | − | 1 100 | y | = | 5966 625 |
| - | 1 100 | y | = | 5966 625 | − | 10261519 1000000 |
| - | 1 100 | y | = | - | 715919 1000000 |
715919 1000000 | = | 1 100 | y |
1 100 | y | = | 715919 1000000 |
| y | = | 715919 1000000 | ÷ | 1 100 |
| = | 715919 1000000 | × | 100 |
| = | 715919 10000 | × | 1 |
| y | = | 715919 10000 |
