1223 | − | 8 | ( | 8 | x | + | 140 | ) | = | 10 | ( | 5 | x | − | 33 | ) | + | 615 |
方程左边 = | 1223 | − | 8 | × | 8 | x | − | 8 | × | 140 |
= | 1223 | − | 64 | x | − | 1120 |
= | 103 | − | 64 | x |
103 | − | 64 | x | = | 10 | ( | 5 | x | − | 33 | ) | + | 615 |
方程右边 = | 10 | × | 5 | x | − | 10 | × | 33 | + | 615 |
= | 50 | x | − | 330 | + | 615 |
= | 50 | x | + | 285 |
103 | − | 64 | x | = | 50 | x | + | 285 |
- | 64 | x | − | 50 | x | = | 285 | − | 103 |
- | 114 | x | = | 285 | − | 103 |
- | 114 | x | = | 182 |
- | 182 | = | 114 | x |
114 | x | = | - | 182 |
x | = | - | 182 | ÷ | 114 |
= | - | 182 | × | 1 114 |
= | - | 91 | × | 1 57 |
x | = | - | 91 57 |
x | = | - 1.596491 |
