3000/(x-3)-3000/x
3000/(x-3)-3000/x
3000/(x-3)-3000/x
3000/(x-3)-3000/x
=【3000x-3000(x-3)】/x(x-3)
=9000/(x²-3x)
3000/(x-3)-3000/x
3000/x-3000/75%x

解方程:5X+(3X+200)=3000
5X+3(X+200)=3000怎么解
3000/x-10 -3000/x=15 36/x -36/x=3 18/x=36/1.25 -6 60/x +240/2x=9 1200/x-1200/x+2 过程一定要清楚空格后面是为了区分开来所以36/x -36/x-3=1 18/x=36/1.25 -6 60/x +240/2x=9 1200/x-1200/x+2=30 不好意思 x-10是分母!1.25是分母!不
x*(-x)3+(-x)*x3

3000/x=3000/1.5x+2 x=?
(x*x-3)*(x*x-3)-x*(x*x-3)-2x*x 因式分解
