( | 5 | ( | 31 | + | x | ) | + | 6 | ) | ÷ | ( | 36 | + | x | ) | = | 24 5 |
方程两边同时乘以: | ( | 36 | + | x | ) |
( | 5 | ( | 31 | + | x | ) | + | 6 | ) | = | 24 5 | ( | 36 | + | x | ) |
5 | ( | 31 | + | x | ) | + | 6 | = | 24 5 | ( | 36 | + | x | ) |
5 | ( | 31 | + | x | ) | + | 6 | = | 24 5 | × | 36 | + | 24 5 | x |
5 | ( | 31 | + | x | ) | + | 6 | = | 864 5 | + | 24 5 | x |
5 | × | 31 | + | 5 | x | + | 6 | = | 864 5 | + | 24 5 | x |
155 | + | 5 | x | + | 6 | = | 864 5 | + | 24 5 | x |
161 | + | 5 | x | = | 864 5 | + | 24 5 | x |
5 | x | − | 24 5 | x | = | 864 5 | − | 161 |
1 5 | x | = | 864 5 | − | 161 |
1 5 | x | = | 59 5 |
x | = | 59 5 | ÷ | 1 5 |
= | 59 5 | × | 5 |
= | 59 | × | 1 |
x | = | 59 |
