1307 100 | c | = | ( | 7 2 | + | c | ) | × | 198 25 |
| Right side of the equation = | 7 2 | × | 198 25 | + | c | × | 198 25 |
| = | 693 25 | + | c | × | 198 25 |
1307 100 | c | = | 693 25 | + | 198 25 | c |
1307 100 | c | − | 198 25 | c | = | 693 25 |
103 20 | c | = | 693 25 |
| c | = | 693 25 | ÷ | 103 20 |
| = | 693 25 | × | 20 103 |
| = | 693 5 | × | 4 103 |
| c | = | 2772 515 |
| c | = | 5.382524 |
