43 25 | × | 98 | + | x | × | 27 10 | = | 2 | ( | 98 | + | x | ) |
| 方程左边 = | 4214 25 | + | x | × | 27 10 |
4214 25 | + | 27 10 | x | = | 2 | ( | 98 | + | x | ) |
| 方程右边 = | 2 | × | 98 | + | 2 | x |
| = | 196 | + | 2 | x |
4214 25 | + | 27 10 | x | = | 196 | + | 2 | x |
27 10 | x | − | 2 | x | = | 196 | − | 4214 25 |
7 10 | x | = | 196 | − | 4214 25 |
7 10 | x | = | 686 25 |
| x | = | 686 25 | ÷ | 7 10 |
| = | 686 25 | × | 10 7 |
| = | 98 5 | × | 2 |
| x | = | 196 5 |
| x | = | 39.2 |
