( | 26293 1000 | + | x | ) | × | 49 20 | = | 26293 1000 | + | 35889 500 | − | x |
方程左边 = | 26293 1000 | × | 49 20 | + | x | × | 49 20 |
= | 1288357 20000 | + | x | × | 49 20 |
1288357 20000 | + | 49 20 | x | = | 26293 1000 | + | 35889 500 | − | x |
方程右边 = | 98071 1000 | − | x |
1288357 20000 | + | 49 20 | x | = | 98071 1000 | − | x |
49 20 | x | + | x | = | 98071 1000 | − | 1288357 20000 |
69 20 | x | = | 98071 1000 | − | 1288357 20000 |
69 20 | x | = | 673063 20000 |
x | = | 673063 20000 | ÷ | 69 20 |
= | 673063 20000 | × | 20 69 |
= | 673063 1000 | × | 1 69 |
x | = | 673063 69000 |
