88 | x | + | 98 | ( | 1200 | − | x | ) | = | 12100 | × | 94 |
方程左边 = | 88 | x | + | 98 | × | 1200 | − | 98 | x |
= | 88 | x | + | 117600 | − | 98 | x |
= | - | 10 | x | + | 117600 |
- | 10 | x | + | 117600 | = | 12100 | × | 94 |
方程右边 = | 1137400 |
- | 10 | x | + | 117600 | = | 1137400 |
- | 10 | x | = | 1137400 | − | 117600 |
- | 10 | x | = | 1019800 |
- | 1019800 | = | 10 | x |
10 | x | = | - | 1019800 |
x | = | - | 1019800 | ÷ | 10 |
= | - | 1019800 | × | 1 10 |
= | - | 101980 | × | 1 |
x | = | - | 101980 |
