10787 10000 | x | ÷ | ( | 20 | + | 1000 | x | ) | = | 1 5000 |
方程两边同时乘以: | ( | 20 | + | 1000 | x | ) |
10787 10000 | x | = | 1 5000 | ( | 20 | + | 1000 | x | ) |
10787 10000 | x | = | 1 5000 | × | 20 | + | 1 5000 | × | 1000 | x |
10787 10000 | x | = | 1 250 | + | 1 5 | x |
10787 10000 | x | − | 1 5 | x | = | 1 250 |
8787 10000 | x | = | 1 250 |
x | = | 1 250 | ÷ | 8787 10000 |
= | 1 250 | × | 10000 8787 |
= | 1 | × | 40 8787 |
x | = | 40 8787 |
x | = | 0.004552 |
