( | X | − | 712414449 50 | ) | ÷ | X | = | 3 10 |
方程两边同时乘以: | X |
( | X | − | 712414449 50 | ) | = | 3 10 | X |
X | − | 712414449 50 | = | 3 10 | X |
X | − | 3 10 | X | = | 712414449 50 |
7 10 | X | = | 712414449 50 |
X | = | 712414449 50 | ÷ | 7 10 |
= | 712414449 50 | × | 10 7 |
= | 712414449 5 | × | 1 7 |
X | = | 712414449 35 |
