x | ÷ | ( | 20 | + | ( | x | − | 24 | ) | ÷ | 2 | ) | = | 3 2 |
方程两边同时乘以: | ( | 20 | + | ( | x | − | 24 | ) | ÷ | 2 | ) |
x | = | 3 2 | ( | 20 | + | ( | x | − | 24 | ) | ÷ | 2 | ) |
x | = | 3 2 | × | 20 | + | 3 2 | ( | x | − | 24 | ) | ÷ | 2 |
x | = | 30 | + | 3 4 | ( | x | − | 24 | ) |
x | = | 30 | + | 3 4 | x | − | 3 4 | × | 24 |
x | = | 30 | + | 3 4 | x | − | 18 |
x | = | 12 | + | 3 4 | x |
x | − | 3 4 | x | = | 12 |
1 4 | x | = | 12 |
x | = | 12 | ÷ | 1 4 |
= | 12 | × | 4 |
x | = | 48 |
