x | × | 88 | + | ( | 117600 | − | 98 | x | ) | = | 1200 | × | 94 | x |
方程左边 = | 88 | x | + | 117600 | − | 98 | x |
= | - | 10 | x | + | 117600 |
- | 10 | x | + | 117600 | = | 1200 | × | 94 | x |
方程右边 = | 112800 | x |
- | 10 | x | + | 117600 | = | 112800 | x |
- | 10 | x | − | 112800 | x | = | - | 117600 |
- | 112810 | x | = | - | 117600 |
117600 | = | 112810 | x |
112810 | x | = | 117600 |
x | = | 117600 | ÷ | 112810 |
= | 117600 | × | 1 112810 |
= | 11760 | × | 1 11281 |
x | = | 11760 11281 |
x | = | 1.042461 |
