1203 100 | c | = | ( | 18 5 | + | c | ) | × | 198 25 |
| Right side of the equation = | 18 5 | × | 198 25 | + | c | × | 198 25 |
| = | 3564 125 | + | c | × | 198 25 |
1203 100 | c | = | 3564 125 | + | 198 25 | c |
1203 100 | c | − | 198 25 | c | = | 3564 125 |
411 100 | c | = | 3564 125 |
| c | = | 3564 125 | ÷ | 411 100 |
| = | 3564 125 | × | 100 411 |
| = | 1188 5 | × | 4 137 |
| c | = | 4752 685 |
