x | ÷ | ( | 94190 | + | x | ) | = | 12 | ÷ | 100 |
方程两边同时乘以: | ( | 94190 | + | x | ) |
x | = | 12 | ÷ | 100 | × | ( | 94190 | + | x | ) |
x | = | 12 | ÷ | 100 | × | 94190 | + | 12 | ÷ | 100 | × | x |
x | = | 56514 5 | + | 3 25 | x |
x | − | 3 25 | x | = | 56514 5 |
22 25 | x | = | 56514 5 |
x | = | 56514 5 | ÷ | 22 25 |
= | 56514 5 | × | 25 22 |
= | 28257 | × | 5 11 |
x | = | 141285 11 |
x | = | 12844.090909 |
