解方程X-2-18X/3=X/9+2
解方程:(x-2)(x^2-6x-9)=x(x-5)(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-8)/(x-3)-(x-9)/(x-4)=(x+7)/(x+8)-(x+2)/(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)
2x+3x=18+4x解方程
解方程x/(x-2)=2x/(x-3)+(1-x)/(x-5x+6)
解方程与不等式(x-3)(x-2)+18=(x+9)(x+1)
解方程(x-3)(x-2)+18=(x+9)(x+1)
方程:(x-3)(x-2)-(x+9)(x+1)=-18的解是_
解方程 (X-3)(X^2+3X+9)-X(X^2+3)-9=9
解方程:2x+9/x+3 - 1/x-3 = 5 - 3x-2/x
