1/7(x-1)=1/7
如果3x*x-x=1那么9x*x*x*x+12x*x*x-3x*x-7x+2001等于多少
已知3x*x-x=1,求6x*x*x+7x*x-5x+2000
(x+7)(x+6)-(x-2)(x+1)=?
X-5+8*X=7*X-2*X-1
(3-x)/(1-x)-(5-x)/(7-x)+(x^2-x)/(x^2-8x+7)=1
(2x-1)/(x-1)(x-2)=(x-5)/(x-2)(x-3) x/2x^2-11x-21=(x+7)/x^2-1
y=(x-1)(x-2)(x-3)(x-4)(x-5)(x-6)(x-7)(x-8)(x-9)(x-10)的导数在x=1
x+3/x+1-x+5/x+3-x+7/x+5+x+9/x+7=0
x/(x-2)+(x-9)/(x-7)=(x+1)/(x-1)+(x-8)/(x-6)谁会解这道方程题
分式方程.x/(x-2)+(x-9)/(x-7)=(x+1)/(x-1)+(x-8)/(x-6)
x/(x-2)+(x+9)/(x-7)=(x+1)/(x-1)+(x-8)/(x-6)怎样解这道方程
解方程:x/(x-2)+(x-9)/(x-7)=(x+1)/(x-1)+(x-8)/(x-6)
