请问这道题咋做 :(x)X (x+1) X (x+2) X (x+3) =360

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
计算(x*x+4x+5)/(x+2)-(x*x+6x+10)/(x+3)+1
解方程(x-2)X(x的平方-6x-9)=x(x-5)X(x-3)
x(x平方-1)+2X平方(X+1)-3X(2X-5)帮个忙
x(x^2-1)+2x^2 *(x+1)-3x*(2x-5)=x(3x^2-4x)-28
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
5x-3(2x+1)=6x-4(5-3x)求x
5x-3(2x+1)=6x-4(5-3x)求x
2(5x-4)-3(x+6)=5(x-1)-x 求x.
(x-3/x-2)-(x-2/x-1)=(x-5/x4) -(x-4/x-3)
麻烦解4道分式方程(20分)(x/2x-5)+(5/5-2x)=1(x+1/x*x-2x)-(1/x)=3/x-2(1-x/5-x)-(5-x/1-x)=8/x*x-6x+5(x+1/x-1)-(4/x*x-1)=1去掉括号,不管前面正负,都不变号~
