解方程:5/x^2-9+2x/x+3=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) 解方程：2x+9/x+3 - 1/x-3 = 5 - 3x-2/x 解方程:2(X-3)(X+5)=X平方+(X+2)(X-2)+(X+7) 解方程 x(2x-4)+3x(x-1)=5x(x-3)+8 解方程 3x/x×x-1+x×x-1/3x=5/2 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(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
