( | 10000 | ÷ | 154 | ) | x | + | ( | 150 | − | 10000 | ÷ | 154 | ) | x | = | 30000 |
方程左边 = | 10000 | ÷ | 154 | × | x | + | ( | 150 | − | 10000 | ÷ | 154 | ) | x |
= | 5000 77 | x | + | ( | 150 | − | 10000 | ÷ | 154 | ) | x |
= | 5000 77 | x | + | 150 | x | − | 10000 | ÷ | 154 | × | x |
= | 5000 77 | x | + | 150 | x | − | 5000 77 | x |
= | 150 | x |
150 | x | = | 30000 |
x | = | 30000 | ÷ | 150 |
= | 30000 | × | 1 150 |
= | 200 | × | 1 |
x | = | 200 |
