331 25 | c | = | ( | c | + | 16 5 | ) | × | 198 25 |
| Right side of the equation = | c | × | 198 25 | + | 16 5 | × | 198 25 |
| = | c | × | 198 25 | + | 3168 125 |
331 25 | c | = | 198 25 | c | + | 3168 125 |
331 25 | c | − | 198 25 | c | = | 3168 125 |
133 25 | c | = | 3168 125 |
| c | = | 3168 125 | ÷ | 133 25 |
| = | 3168 125 | × | 25 133 |
| = | 3168 5 | × | 1 133 |
| c | = | 3168 665 |
| c | = | 4.76391 |
