方程两边同时乘以: | ( | 1 | − | x | ) |
59 20 | ( | 1 | − | x | ) | = | x | × | 2 |
59 20 | × | 1 | − | 59 20 | x | = | x | × | 2 |
59 20 | − | 59 20 | x | = | x | × | 2 |

- | 99 20 | x | = | - | 59 20 |
59 20 | = | 99 20 | x |
99 20 | x | = | 59 20 |
x | = | 59 20 | ÷ | 99 20 |
= | 59 20 | × | 20 99 |
= | 59 | × | 1 99 |
x | = | 59 99 |
