( | 4823 125 | + | x | ) | × | 5 2 | = | 4823 125 | + | 8496 125 | − | x |
方程左边 = | 4823 125 | × | 5 2 | + | x | × | 5 2 |
= | 4823 50 | + | x | × | 5 2 |
4823 50 | + | 5 2 | x | = | 4823 125 | + | 8496 125 | − | x |
方程右边 = | 13319 125 | − | x |
4823 50 | + | 5 2 | x | = | 13319 125 | − | x |
5 2 | x | + | x | = | 13319 125 | − | 4823 50 |
7 2 | x | = | 13319 125 | − | 4823 50 |
7 2 | x | = | 2523 250 |
x | = | 2523 250 | ÷ | 7 2 |
= | 2523 250 | × | 2 7 |
= | 2523 125 | × | 1 7 |
x | = | 2523 875 |
