( | 893 1000 | − | x | ) | × | 600 | + | 1 5 | = | 150 |
方程左边 = | 893 1000 | × | 600 | − | x | × | 600 | + | 1 5 |
= | 2679 5 | − | x | × | 600 | + | 1 5 |
= | 536 | − | 600 | x |
536 | − | 600 | x | = | 150 |
- | 600 | x | = | 150 | − | 536 |
- | 600 | x | = | - | 386 |
386 | = | 600 | x |
600 | x | = | 386 |
x | = | 386 | ÷ | 600 |
= | 386 | × | 1 600 |
= | 193 | × | 1 300 |
x | = | 193 300 |
x | = | 0.643333 |
