( | x | − | 2 25 | ) | ÷ | ( | 1 10 | − | x | ) | = | 100 | ÷ | 33 |
方程两边同时乘以: | ( | 1 10 | − | x | ) |
( | x | − | 2 25 | ) | = | 100 | ÷ | 33 | × | ( | 1 10 | − | x | ) |
x | − | 2 25 | = | 100 | ÷ | 33 | × | ( | 1 10 | − | x | ) |
x | − | 2 25 | = | 100 | ÷ | 33 | × | 1 10 | − | 100 | ÷ | 33 | × | x |
x | − | 2 25 | = | 10 33 | − | 100 33 | x |
x | + | 100 33 | x | = | 10 33 | + | 2 25 |
133 33 | x | = | 10 33 | + | 2 25 |
133 33 | x | = | 316 825 |
x | = | 316 825 | ÷ | 133 33 |
= | 316 825 | × | 33 133 |
= | 316 25 | × | 1 133 |
x | = | 316 3325 |
x | = | 0.095038 |
