( | 19701 500 | + | x | ) | × | 9 4 | = | 19701 500 | + | 9013 125 | − | x |
方程左边 = | 19701 500 | × | 9 4 | + | x | × | 9 4 |
= | 177309 2000 | + | x | × | 9 4 |
177309 2000 | + | 9 4 | x | = | 19701 500 | + | 9013 125 | − | x |
方程右边 = | 55753 500 | − | x |
177309 2000 | + | 9 4 | x | = | 55753 500 | − | x |
9 4 | x | + | x | = | 55753 500 | − | 177309 2000 |
13 4 | x | = | 55753 500 | − | 177309 2000 |
13 4 | x | = | 45703 2000 |
x | = | 45703 2000 | ÷ | 13 4 |
= | 45703 2000 | × | 4 13 |
= | 45703 500 | × | 1 13 |
x | = | 45703 6500 |
x | = | 7.031231 |
