(x-14529.91)/x/17%=2%解:x=16467.20可是我求出来的是x=14579.48

问题描述:

(x-14529.91)/x/17%=2%解:x=16467.20可是我求出来的是x=14579.48

(x-14529.91)/x/17%=2%
17%(x-14529.91)=2%x
(17%-2%)x=17%*14529.91
x=17*14529.91/15
=16467.23你用的什么方法,看不懂(x-14529.91)/x/17%=2%17%(x-14529.91)/x=2%17%(x-14529.91)=2%x17%x-17%*14529.91=2%x17%x-2%x=17%*14529.9115%x=17%*14529.91x=17%*14529.91/15% =16467.23第二步不懂不是除0.17吗,怎么又乘了这个题少了个括号(x-14529.91)/(x/17%)=2%式子应该是这样,你应该就看的懂了 除以一个分数,相当于乘以这个分数的倒数
