88 | x | + | 98 | ( | 1200 | − | x | ) | = | 12100 | × | 94 | x |
方程左边 = | 88 | x | + | 98 | × | 1200 | − | 98 | x |
= | 88 | x | + | 117600 | − | 98 | x |
= | - | 10 | x | + | 117600 |
- | 10 | x | + | 117600 | = | 12100 | × | 94 | x |
方程右边 = | 1137400 | x |
- | 10 | x | + | 117600 | = | 1137400 | x |
- | 10 | x | − | 1137400 | x | = | - | 117600 |
- | 1137410 | x | = | - | 117600 |
117600 | = | 1137410 | x |
1137410 | x | = | 117600 |
x | = | 117600 | ÷ | 1137410 |
= | 117600 | × | 1 1137410 |
= | 11760 | × | 1 113741 |
x | = | 11760 113741 |
x | = | 0.103393 |
