(1) 4X+10Y=3.6 15X-10Y=8 谢谢! 开什么玩笑,就这题还用人帮,是不是想盗别人QQ号啊. 哇,太简单了吧!你刚初一吧!或者小学
x/(120-x)=x/60
(x+x)+(x-x)+(x/x)=11.2
(58-x)+(x*1.95)=60
12x(x+x)=60 X=?
x*x*x*x+2008x*x+2007x+2008(提示:x*x*x-1=(x-1)*(x*x+x+1))
12=( )X( )X( ) 60=( )X( )x( )X( )
若1+x+x*x+x*x*x=0,求x+x*x+x*x*x+.+x(2000次幂)
请问这道题咋做 :(x)X (x+1) X (x+2) X (x+3) =360

45X(x+1)=60X 怎么解
60+x=4x(12+x)怎么解
x-140-(x-140)×60%=X÷6
已知x除以(x*x-x+1)=7,求x*x除以(x*x*x*x+x*x+1)的值
45X=60(X-1)
1.5x(x-3)=60
(1000-x)×60=100x
40(x+60)=70x
