(1-5\6):x=3.75
(1) x-3/x-2 - x-5/x-4=x-7/x-6 - x-9/x-8
3/x-1=4/x 6/x+1=x+5/x(x+1)
6/(x+1)=(x+5)/[x(x+1)] (3-x)/(x-4)+1/(4-x)=1 2/(1+x)-3/(1-x)
5x-3(2x+1)=6x-4(5-3x)求x
解方程x/(x-2)=2x/(x-3)+(1-x)/(x-5x+6)
(x/x-1)+(5x-2)/x*x-x=1 求x(有图)
已知3x*x-x=1,求6x*x*x+7x*x-5x+2000
X-(X/2)+(X/3)-(X/4)+(X/5)-(X/6)=1
求函数Y=(X·X-2X-1)/(X·X-5X-6)的值域?
解方程①(x+3/x-1)²-5(x+3/x-1)+6=0 ②x²-2/x+3-6x+18/x
利用换元法解方程[x/(x-2)]²-5[x/(x-2)]+6=01/(x²-2x)+2x=x
x+1分之x+2减去x+3分之x+4=x+5分之x+6减去X+7分之x+8 (解方程)
