x | ÷ | ( | 7008 | − | x | ) | = | 199 200 |
方程两边同时乘以: | ( | 7008 | − | x | ) |
x | = | 199 200 | ( | 7008 | − | x | ) |
x | = | 199 200 | × | 7008 | − | 199 200 | x |
x | = | 174324 25 | − | 199 200 | x |
x | + | 199 200 | x | = | 174324 25 |
399 200 | x | = | 174324 25 |
x | = | 174324 25 | ÷ | 399 200 |
= | 174324 25 | × | 200 399 |
= | 58108 | × | 8 133 |
x | = | 464864 133 |
x | = | 3495.218045 |
