1221 100 | c | = | ( | 16 5 | + | c | ) | × | 198 25 |
| Right side of the equation = | 16 5 | × | 198 25 | + | c | × | 198 25 |
| = | 3168 125 | + | c | × | 198 25 |
1221 100 | c | = | 3168 125 | + | 198 25 | c |
1221 100 | c | − | 198 25 | c | = | 3168 125 |
429 100 | c | = | 3168 125 |
| c | = | 3168 125 | ÷ | 429 100 |
| = | 3168 125 | × | 100 429 |
| = | 96 5 | × | 4 13 |
| c | = | 384 65 |
| c | = | 5.907692 |
