1213 100 | c | = | ( | 33 10 | + | c | ) | × | 897 100 |
| Right side of the equation = | 33 10 | × | 897 100 | + | c | × | 897 100 |
| = | 29601 1000 | + | c | × | 897 100 |
1213 100 | c | = | 29601 1000 | + | 897 100 | c |
1213 100 | c | − | 897 100 | c | = | 29601 1000 |
79 25 | c | = | 29601 1000 |
| c | = | 29601 1000 | ÷ | 79 25 |
| = | 29601 1000 | × | 25 79 |
| = | 29601 40 | × | 1 79 |
| c | = | 29601 3160 |
| c | = | 9.367405 |
