522 5 | + | ( | 22 | − | x | ) | × | 43 10 | = | ( | 50 | + | 13 2 | x | ) | ÷ | 3 2 |
方程左边 = | 522 5 | + | 22 | × | 43 10 | − | x | × | 43 10 |
= | 522 5 | + | 473 5 | − | x | × | 43 10 |
= | 199 | − | 43 10 | x |
199 | − | 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 |
199 | − | 43 10 | x | = | 100 3 | + | 13 3 | x |
- | 43 10 | x | − | 13 3 | x | = | 100 3 | − | 199 |
- | 259 30 | x | = | 100 3 | − | 199 |
- | 259 30 | x | = | - | 497 3 |
497 3 | = | 259 30 | x |
259 30 | x | = | 497 3 |
x | = | 497 3 | ÷ | 259 30 |
= | 497 3 | × | 30 259 |
= | 71 | × | 10 37 |
x | = | 710 37 |
x | = | 19.189189 |
