( | 236 | + | 5 | X | ) | ÷ | ( | 51 | + | X | ) | = | 24 5 |
方程两边同时乘以: | ( | 51 | + | X | ) |
( | 236 | + | 5 | X | ) | = | 24 5 | ( | 51 | + | X | ) |
236 | + | 5 | X | = | 24 5 | ( | 51 | + | X | ) |
236 | + | 5 | X | = | 24 5 | × | 51 | + | 24 5 | X |
236 | + | 5 | X | = | 1224 5 | + | 24 5 | X |
5 | X | − | 24 5 | X | = | 1224 5 | − | 236 |
1 5 | X | = | 1224 5 | − | 236 |
1 5 | X | = | 44 5 |
X | = | 44 5 | ÷ | 1 5 |
= | 44 5 | × | 5 |
= | 44 | × | 1 |
X | = | 44 |
