( | 24 | − | 8 | x | ) | ÷ | 7 | = | ( | 5 | x | + | 3 | ) | ÷ | 13 | − | 1 |
方程左边 = | 24 | × | 1 7 | − | 8 | x | × | 1 7 |
= | 24 7 | − | 8 7 | x |
24 7 | − | 8 7 | x | = | ( | 5 | x | + | 3 | ) | ÷ | 13 | − | 1 |
方程右边 = | 5 | x | × | 1 13 | + | 3 | × | 1 13 | − | 1 |
= | 5 13 | x | + | 3 13 | − | 1 |
= | 5 13 | x | − | 10 13 |
24 7 | − | 8 7 | x | = | 5 13 | x | − | 10 13 |
- | 8 7 | x | − | 5 13 | x | = | - | 10 13 | − | 24 7 |
- | 139 91 | x | = | - | 10 13 | − | 24 7 |
- | 139 91 | x | = | - | 382 91 |
382 91 | = | 139 91 | x |
139 91 | x | = | 382 91 |
x | = | 382 91 | ÷ | 139 91 |
= | 382 91 | × | 91 139 |
= | 382 | × | 1 139 |
x | = | 382 139 |
x | = | 2.748201 |
