x | ÷ | ( | x | + | 713 | ) | = | 73 100 |
方程两边同时乘以: | ( | x | + | 713 | ) |
x | = | 73 100 | ( | x | + | 713 | ) |
x | = | 73 100 | x | + | 73 100 | × | 713 |
x | = | 73 100 | x | + | 52049 100 |
x | − | 73 100 | x | = | 52049 100 |
27 100 | x | = | 52049 100 |
x | = | 52049 100 | ÷ | 27 100 |
= | 52049 100 | × | 100 27 |
= | 52049 | × | 1 27 |
x | = | 52049 27 |
x | = | 1927.740741 |
