a | + | ( | a | − | 100 | ) | × | 13 25 | = | 7553 10 |
方程左边 = | a | + | a | × | 13 25 | − | 100 | × | 13 25 |
= | a | + | a | × | 13 25 | − | 52 |
= | 38 25 | a | − | 52 |
38 25 | a | − | 52 | = | 7553 10 |
38 25 | a | = | 7553 10 | + | 52 |
38 25 | a | = | 8073 10 |
a | = | 8073 10 | ÷ | 38 25 |
= | 8073 10 | × | 25 38 |
= | 8073 2 | × | 5 38 |
