10787 10000 | x | ÷ | ( | 40 | + | 1000 | x | ) | = | 1 20000 |
方程两边同时乘以: | ( | 40 | + | 1000 | x | ) |
10787 10000 | x | = | 1 20000 | ( | 40 | + | 1000 | x | ) |
10787 10000 | x | = | 1 20000 | × | 40 | + | 1 20000 | × | 1000 | x |
10787 10000 | x | = | 1 500 | + | 1 20 | x |
10787 10000 | x | − | 1 20 | x | = | 1 500 |
10287 10000 | x | = | 1 500 |
x | = | 1 500 | ÷ | 10287 10000 |
= | 1 500 | × | 10000 10287 |
= | 1 | × | 20 10287 |
x | = | 20 10287 |
x | = | 0.001944 |
