( | X | − | 3373933039 50 | ) | ÷ | X | = | 1 100 |
方程两边同时乘以: | X |
( | X | − | 3373933039 50 | ) | = | 1 100 | X |
X | − | 3373933039 50 | = | 1 100 | X |
X | − | 1 100 | X | = | 3373933039 50 |
99 100 | X | = | 3373933039 50 |
X | = | 3373933039 50 | ÷ | 99 100 |
= | 3373933039 50 | × | 100 99 |
= | 3373933039 | × | 2 99 |
X | = | 6747866078 99 |
