(x+1)/(x+2)+(x+8)/(x+9)解答x+1/x+2+x+8/x+9=x+2/x+3+x+7/x+8 （1） x-3/x-2 - x-5/x-4=x-7/x-6 - x-9/x-8(2) 已知x+3/(x-2)^2=A/x-2 + B/(x-2)^2 ,求A和B的值. a+x/x+1 ,x/x^2-2x-3 ,a/x^2+4x+3 若a^2x=√2 -1,则(a^3x+a^-3x)/(a^x+a^-x)等于? 若2x-3y+4=0则x（x*x-1)+x(5-x*x)-6y+7 已知a(x*x+x-c)+b(2x*x-x-2)=7x*x+4x+3x.求a,b,c的值 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, 解下列分式方程:(1)X/(X-2)+(X-9)/(X-7)=(X+1)/(X-1)+(X-8)/(X-6)还有几道 (2)(X+2)/(X+1)-(X+4)/(X+3)=(X+6)/(X+5)-(X+8)/(X+7) 解关于X的方程(2a)/(x-1)=2-a过程讲仔细点啊!
