X | ÷ | 135 | − | ( | 1000 | − | X | ) | ÷ | 200 | = | 247 100 |
方程左边 = | 1 135 | X | − | 1000 | × | 1 200 | + | X | × | 1 200 |
= | 1 135 | X | − | 5 | + | X | × | 1 200 |
= | 67 5400 | X | − | 5 |
67 5400 | X | − | 5 | = | 247 100 |
67 5400 | X | = | 247 100 | + | 5 |
67 5400 | X | = | 747 100 |
X | = | 747 100 | ÷ | 67 5400 |
= | 747 100 | × | 5400 67 |
= | 747 | × | 54 67 |
X | = | 40338 67 |
X | = | 602.059701 |
