66 | ÷ | ( | 92 | + | x | ) | = | 309 500 |
方程两边同时乘以: | ( | 92 | + | x | ) |
66 | = | 309 500 | ( | 92 | + | x | ) |
66 | = | 309 500 | × | 92 | + | 309 500 | x |
66 | = | 7107 125 | + | 309 500 | x |
- | 309 500 | x | = | 7107 125 | − | 66 |
- | 309 500 | x | = | - | 1143 125 |
1143 125 | = | 309 500 | x |
309 500 | x | = | 1143 125 |
x | = | 1143 125 | ÷ | 309 500 |
= | 1143 125 | × | 500 309 |
= | 381 | × | 4 103 |
x | = | 1524 103 |
x | = | 14.796117 |
