解方程：9x-3(x-2)=6x+2

解方程：(x-2)(x^2-6x-9)=x(x-5)(x-3) 解方程:(x+3)/(x+2)-(x+5)/(x+4)=(x+7)/(x+6)-(x+9)/(x+8) 解方程（x-2）X（x的平方-6x-9）=x(x-5)X(x-3) 解方程x/(x-2)=2x/(x-3)+(1-x)/(x-5x+6) x/(x-2)+(x+1)/(x-6)=2x/(x-3) 解分式方程 解方程(x+1/x+2)-(x+2/x+3)=(x+5/x+6)-(x+6/x+7) 解方程：x+2/x+1-x+3/x+2=x+6/x+5-x+7/x+6 解方程(x-2)/(x-3)-(x-3)/(x-4)=(x-5)/(x-6)-(x-6)/(x-7) 解方程：x/(x-2)+(x-9)/(x-7)=(x+1)/(x-1)+(x-8)/(x-6) 解方程】(x+8)/(x-3)-(x-9)/(x-4)=(x+7)/(x+8)-(x+2)/(x+3) 解方程：（x-8）/(x-3)-(x-9)/(x-4)=(x+7)/(x+8)-(x+2)/(x+3) 解方程：2x+4x+6x...+100x=1-(x+3x+5x+...+99x)
