( | x | − | 650 | ) | ÷ | 1333 | = | ( | x | − | 350 | ) | ÷ | 2400 |
方程左边 = | x | × | 1 1333 | − | 650 | × | 1 1333 |
= | x | × | 1 1333 | − | 650 1333 |
1 1333 | x | − | 650 1333 | = | ( | x | − | 350 | ) | ÷ | 2400 |
方程右边 = | x | × | 1 2400 | − | 350 | × | 1 2400 |
= | x | × | 1 2400 | − | 7 48 |
1 1333 | x | − | 650 1333 | = | 1 2400 | x | − | 7 48 |
1 1333 | x | − | 1 2400 | x | = | - | 7 48 | + | 650 1333 |
1067 3199200 | x | = | - | 7 48 | + | 650 1333 |
1067 3199200 | x | = | 21869 63984 |
x | = | 21869 63984 | ÷ | 1067 3199200 |
= | 21869 63984 | × | 3199200 1067 |
= | 21869 | × | 50 1067 |
x | = | 1093450 1067 |
x | = | 1024.789128 |
