( | 2 | x | − | 1 | ) | ÷ | ( | 3 | x | + | 4 | ) | = | 60 100 |
方程两边同时乘以: | ( | 3 | x | + | 4 | ) |
( | 2 | x | − | 1 | ) | = | 60 100 | ( | 3 | x | + | 4 | ) |
2 | x | − | 1 | = | 60 100 | ( | 3 | x | + | 4 | ) |
2 | x | − | 1 | = | 60 100 | × | 3 | x | + | 60 100 | × | 4 |
2 | x | − | 1 | = | 9 5 | x | + | 12 5 |
2 | x | − | 9 5 | x | = | 12 5 | + | 1 |
1 5 | x | = | 12 5 | + | 1 |
1 5 | x | = | 17 5 |
x | = | 17 5 | ÷ | 1 5 |
= | 17 5 | × | 5 |
= | 17 | × | 1 |
x | = | 17 |
