416 5 | + | ( | 21 | − | x | ) | × | 43 10 | = | ( | 50 | + | 13 2 | x | ) | ÷ | 3 2 |
方程左边 = | 416 5 | + | 21 | × | 43 10 | − | x | × | 43 10 |
= | 416 5 | + | 903 10 | − | x | × | 43 10 |
= | 347 2 | − | 43 10 | x |
347 2 | − | 43 10 | x | = | ( | 50 | + | 13 2 | x | ) | ÷ | 3 2 |
方程右边 = | 50 | × | 2 3 | + | 13 2 | x | × | 2 3 |
= | 100 3 | + | 13 3 | x |
347 2 | − | 43 10 | x | = | 100 3 | + | 13 3 | x |
- | 43 10 | x | − | 13 3 | x | = | 100 3 | − | 347 2 |
- | 259 30 | x | = | 100 3 | − | 347 2 |
- | 259 30 | x | = | - | 841 6 |
841 6 | = | 259 30 | x |
259 30 | x | = | 841 6 |
x | = | 841 6 | ÷ | 259 30 |
= | 841 6 | × | 30 259 |
= | 841 | × | 5 259 |
x | = | 4205 259 |
