263 20 | c | = | ( | 33 10 | + | c | ) | × | 797 100 |
| Right side of the equation = | 33 10 | × | 797 100 | + | c | × | 797 100 |
| = | 26301 1000 | + | c | × | 797 100 |
263 20 | c | = | 26301 1000 | + | 797 100 | c |
263 20 | c | − | 797 100 | c | = | 26301 1000 |
259 50 | c | = | 26301 1000 |
| c | = | 26301 1000 | ÷ | 259 50 |
| = | 26301 1000 | × | 50 259 |
| = | 26301 20 | × | 1 259 |
| c | = | 26301 5180 |
| c | = | 5.077413 |
