( | X | − | 22201783 20 | ) | ÷ | X | = | 2 125 |
方程两边同时乘以: | X |
( | X | − | 22201783 20 | ) | = | 2 125 | X |
X | − | 22201783 20 | = | 2 125 | X |
X | − | 2 125 | X | = | 22201783 20 |
123 125 | X | = | 22201783 20 |
X | = | 22201783 20 | ÷ | 123 125 |
= | 22201783 20 | × | 125 123 |
= | 22201783 4 | × | 25 123 |
X | = | 555044575 492 |
