247 100 | x | ÷ | ( | 1 | + | 147 100 | x | ) | = | 2 5 |
方程两边同时乘以: | ( | 1 | + | 147 100 | x | ) |
247 100 | x | = | 2 5 | ( | 1 | + | 147 100 | x | ) |
247 100 | x | = | 2 5 | × | 1 | + | 2 5 | × | 147 100 | x |
247 100 | x | = | 2 5 | + | 147 250 | x |
247 100 | x | − | 147 250 | x | = | 2 5 |
941 500 | x | = | 2 5 |
x | = | 2 5 | ÷ | 941 500 |
= | 2 5 | × | 500 941 |
= | 2 | × | 100 941 |
x | = | 200 941 |
x | = | 0.21254 |
