1315 | − | 6 | ( | 3 | x | + | 95 | ) | = | 529 | − | 7 | ( | 120 | − | 2 | x | ) |
方程左边 = | 1315 | − | 6 | × | 3 | x | − | 6 | × | 95 |
= | 1315 | − | 18 | x | − | 570 |
= | 745 | − | 18 | x |
745 | − | 18 | x | = | 529 | − | 7 | ( | 120 | − | 2 | x | ) |
方程右边 = | 529 | − | 7 | × | 120 | + | 7 | × | 2 | x |
= | 529 | − | 840 | + | 14 | x |
= | - | 311 | + | 14 | x |
745 | − | 18 | x | = | - | 311 | + | 14 | x |
- | 18 | x | − | 14 | x | = | - | 311 | − | 745 |
- | 32 | x | = | - | 311 | − | 745 |
- | 32 | x | = | - | 1056 |
1056 | = | 32 | x |
32 | x | = | 1056 |
x | = | 1056 | ÷ | 32 |
= | 1056 | × | 1 32 |
= | 33 | × | 1 |
x | = | 33 |
