(x-1)/2=(4x+2)/5-2(x-1)
(1) x-3/x-2 - x-5/x-4=x-7/x-6 - x-9/x-8
(x/x-1)+(5x-2)/x*x-x=1 求x(有图)
(x+2/x+1)-(x+4/x+3)-(x+3/x+2)+(x+5/x+4)
计算(x*x+4x+5)/(x+2)-(x*x+6x+10)/(x+3)+1
x(x^2-1)+2x^2 *(x+1)-3x*(2x-5)=x(3x^2-4x)-28
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
x^5+x^4 = (x^3-x)(x^2+x+1)+x^2+x
先化简再求值先化简再求值:(x-x/x+1)(x+1/x^2+4x+4)(x^2-4/x^2-2x),其中x=-0.5
(x-1)/x -(1-x)/(x+1)=(5x-5)/(2x+2) x等于多少
X-(X/2)+(X/3)-(X/4)+(X/5)-(X/6)=1
方程 3x(7-2x)+5x(2x-1)=4x(x-3)+56
