(1) x-3/x-2 - x-5/x-4=x-7/x-6 - x-9/x-8
(先化简后求值)(3x/x+2-x/x-2)+2x/x^2-4,x=4-根号5,
(x/x-1)+(5x-2)/x*x-x=1 求x(有图)
5x/(x+3)(x+2)+(2x-5)/(x-4)(x+3)=(7x-70)/(x+2)(x+4)
5x+3=x-4,4y+11=22,11x+68-2x=100-9x,0.1x/0.2-(0.27x+0.18)/0.0
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
(4x+2)/x+(4x-22)/(x-5)=(x-6)/(x-4)+(7x+9)/(x+1)
