列出详细解题过程
8%-x/8%-12%=1134-956/1134-887
(8%-x)/(8%-12%)=(1134-956)/(1134-887)
(8%-x)/【-0.04】=178/247
247*【8%-x】=178*【-0.04】
19.76-247x=-7.12
-247x=-26.88
x=0.1088
8%-x/8%-12%=1134-956/1134-887
(8%-x)/(8%-12%)=(1134-956)/(1134-887)
(8%-x)/【-0.04】=178/247
247*【8%-x】=178*【-0.04】
19.76-247x=-7.12
-247x=-26.88
x=0.1088
如果
(8%-x)/(8%-12%)=(1134-956)/(1134-887)
那么
-8%/4%+x/4%=178/247
25x=178/247+2=672/247
x=672/6175
