方程左边 = | 11032 25 | + | 302 25 | c |
11032 25 | + | 302 25 | c | = | ( | 56 | + | c | ) | × | 399 50 |
方程右边 = | 56 | × | 399 50 | + | c | × | 399 50 |
= | 11172 25 | + | c | × | 399 50 |
11032 25 | + | 302 25 | c | = | 11172 25 | + | 399 50 | c |
302 25 | c | − | 399 50 | c | = | 11172 25 | − | 11032 25 |
41 10 | c | = | 11172 25 | − | 11032 25 |
41 10 | c | = | 28 5 |
c | = | 28 5 | ÷ | 41 10 |
= | 28 5 | × | 10 41 |
= | 28 | × | 2 41 |
