x | × | 75 200 | + | ( | 1 | − | x | ) | ( | - | 12 100 | ) | = | 5 100 |
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 | = | 5 100 |
99 200 | x | = | 5 100 | + | 3 25 |
99 200 | x | = | 17 100 |
x | = | 17 100 | ÷ | 99 200 |
= | 17 100 | × | 200 99 |
= | 17 | × | 2 99 |
x | = | 34 99 |
x | = | 0.343434 |
