{(8000-X)/160+x/120)}×480=60×480
24000-3X+4X=28800
X=28800-24000
X=4800
x/(120-x)=x/60
(120- x/10 ×6)(160 x)=19380(120-x/10 ×6)(160 x)=19380
解方程(x-2)X(x的平方-6x-9)=x(x-5)X(x-3)
X[X/(Y+X)+X/(X-Y)]=120/288 求X/Y
x²+6x+ =(x+ )² x²-x+ =(x- )²
3/x-1=4/x 6/x+1=x+5/x(x+1)
(x+x)+(x-x)+(x/x)=11.2
x-(x-140)×160%-1/6x=140请详写,还有一题5x-(120-x)×3.75=162.5

(2x•x+x•x+2x•x)•2+x•x•6+2x•x•4=600
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-
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
2x-6/4-4x+x^2/(x+2)*x^2-4/3-x,其中x=-1
(x-2)(x²-6x-9)-x(x²-2x-15),其中x=1/3
x/(x-2)-(1-x ² )/(x ² -5x+6)=(2-x)/(x-3) 解方程,急
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,
先化简再求值 (x-2)(x-6x-9)-x(x-2x-15),其中先化简再求值 (x-2)(x-6x-9)-x(x-2x-15),其中x=6分之一
