( | 19701 500 | + | x | ) | × | 11 5 | = | 19701 500 | + | 9013 125 | − | x |
方程左边 = | 19701 500 | × | 11 5 | + | x | × | 11 5 |
= | 216711 2500 | + | x | × | 11 5 |
216711 2500 | + | 11 5 | x | = | 19701 500 | + | 9013 125 | − | x |
方程右边 = | 55753 500 | − | x |
216711 2500 | + | 11 5 | x | = | 55753 500 | − | x |
11 5 | x | + | x | = | 55753 500 | − | 216711 2500 |
16 5 | x | = | 55753 500 | − | 216711 2500 |
16 5 | x | = | 31027 1250 |
x | = | 31027 1250 | ÷ | 16 5 |
= | 31027 1250 | × | 5 16 |
= | 31027 250 | × | 1 16 |
x | = | 31027 4000 |
x | = | 7.75675 |
