x | × | 75 200 | + | ( | 1 | − | x | ) | ( | - | 12 100 | ) | = | 0 |
方程左边 = | 75 200 | x | + | 1 | ( | - | 12 100 | ) | − | x | ( | - | 12 100 | ) |
= | 75 200 | x | − | 1 | × | 12 100 | − | x | ( | - | 12 100 | ) |
= | 75 200 | x | − | 3 25 | − | x | ( | - | 12 100 | ) |
= | 75 200 | x | − | 3 25 | + | x | × | 12 100 |
= | 99 200 | x | − | 3 25 |
99 200 | x | − | 3 25 | = | 0 |
99 200 | x | = | 0 | + | 3 25 |
99 200 | x | = | 3 25 |
x | = | 3 25 | ÷ | 99 200 |
= | 3 25 | × | 200 99 |
= | 1 | × | 8 33 |
x | = | 8 33 |
x | = | 0.242424 |
