( | x | × | 85 100 | + | ( | 500 | − | x | ) | × | 27 200 | ) | ÷ | 500 | = | 15 100 |
方程左边 = | x | × | 85 100 | × | 1 500 | + | ( | 500 | − | x | ) | × | 27 200 | × | 1 500 |
= | x | × | 17 10000 | + | ( | 500 | − | x | ) | × | 27 100000 |
= | 17 10000 | x | + | 500 | × | 27 100000 | − | x | × | 27 100000 |
= | 17 10000 | x | + | 27 200 | − | x | × | 27 100000 |
= | 143 100000 | x | + | 27 200 |
143 100000 | x | + | 27 200 | = | 15 100 |
143 100000 | x | = | 15 100 | − | 27 200 |
143 100000 | x | = | 3 200 |
x | = | 3 200 | ÷ | 143 100000 |
= | 3 200 | × | 100000 143 |
= | 3 | × | 500 143 |
x | = | 1500 143 |
x | = | 10.48951 |
