解下列方程!就三道!解下列方程.1、x/x-2 - 1-x²/x²-5x = 2x/x-3(x/x-2 - 1-x²不是一起的!)2、5x/x²+x-6 - 5-2x/x²-x-12=7x-10/x²-6x+8(5x/x²+x-6 - 5-2x不是一起的!)3、x-4/x-5 + x-8/x-9=x-7/x-
x+5/x+1-3x-3/x+5=8x+28/x^2+4X-5-2(x+5)/(x+1)-(3x-3)/(x+5)=(8x+28)/(x^2+4X-5)-2
1.(1/X-1 )-2=X^-3X/X^-12.(X/X+1)^+5(X/X+1)+6=03.(8(X^+2X)/X^-1)+ 3(X^-1)/X^+2x
x/(x-2)-(1-x ² )/(x ² -5x+6)=(2-x)/(x-3) 解方程,急

解方程x/(x-2)=2x/(x-3)+(1-x)/(x-5x+6)
x(x-2)-2x(x+1)-3x(x-5) 其中x=负½
(x-3/x-2)-(x-2/x-1)=(x-5/x4) -(x-4/x-3)
x(x+1)+(x+2)+(x+3)+(x+4)+(x+5) = 27求x
请问这道题咋做 :(x)X (x+1) X (x+2) X (x+3) =360
求:(x-2)(x²-6x-9)-x(x-3)(x-5)其中x=三分之一.以及x²(x-1)-x(x²+x-1)其中x=二分之一的答案
x(x^2-1)+2x^2 *(x+1)-3x*(2x-5)=x(3x^2-4x)-28
f(x,-x)=x^2+2x,fx(x,-x)=5x+1,则fy(x,-x)=
(2x-2)(x-1)=0 x(x-5)=5x-10
x+2/x+1-x+4/x+3=x+6/x+5-x+8/x+7 x=?
5x-3(2x+1)=6x-4(5-3x)求x
5x-3(2x+1)=6x-4(5-3x)求x
