江枫月奴缠绵:4/11x+112/17（4/11x+5）=x

4/11x+112/17（4/11x+5）=x x^11x^18/[-x(-x^2)^3]^4==??? 11*（6-x)/3*(x-4)=10*(5-x)/3*(x-4)-5(6-x)/(x-2) 求x. 已知x+1/x=3,求x^4+3x^3-16x^2-17的值 x-（4/11x+5）/（4/11x+5）=27/17怎么解？ 问几道题目：1.(2*x*x*x+x*x-11x-5)/(x+2)的余式是 . 已知X^2-11X+1=0,求X^2+1/X^2和X^2/(X^4+1) 谁会解这道题：(X-5)/(X-7)+(X-2)/(X-4)=(X-3)/(X-5)+(X-4)/(X-6)求X的值 计算[(x-1)/(x-2)-(x-2)(x-3)-(x-3)/(x-4)+(x-4)(x-5)]/(2x-7) 4x^2+4x-(11/25)=0
