( | ( | x | − | 168263 20 | ) | × | 3 4 | ) | ÷ | ( | 30000 | × | 9 10 | ) | = | 3 25 |
方程两边同时乘以: | ( | 30000 | × | 9 10 | ) |
( | ( | x | − | 168263 20 | ) | × | 3 4 | ) | = | 3 25 | ( | 30000 | × | 9 10 | ) |
( | x | − | 168263 20 | ) | × | 3 4 | = | 3 25 | ( | 30000 | × | 9 10 | ) |
( | x | − | 168263 20 | ) | × | 3 4 | = | 3 25 | × | 30000 | × | 9 10 |
( | x | − | 168263 20 | ) | × | 3 4 | = | 3240 |
x | × | 3 4 | − | 168263 20 | × | 3 4 | = | 3240 |
x | × | 3 4 | − | 504789 80 | = | 3240 |
3 4 | x | = | 3240 | + | 504789 80 |
3 4 | x | = | 763989 80 |
x | = | 763989 80 | ÷ | 3 4 |
= | 763989 80 | × | 4 3 |
