1307 100 | c | = | ( | 33 10 | + | c | ) | × | 79 10 |
| Right side of the equation = | 33 10 | × | 79 10 | + | c | × | 79 10 |
| = | 2607 100 | + | c | × | 79 10 |
1307 100 | c | = | 2607 100 | + | 79 10 | c |
1307 100 | c | − | 79 10 | c | = | 2607 100 |
517 100 | c | = | 2607 100 |
| c | = | 2607 100 | ÷ | 517 100 |
| = | 2607 100 | × | 100 517 |
| = | 237 | × | 1 47 |
| c | = | 237 47 |
| c | = | 5.042553 |
