6x+3/2x+=9 2x-4/3x=1/2 x+9/2=12 这方程怎么解
解方程:(x+3)/(x+2)-(x+5)/(x+4)=(x+7)/(x+6)-(x+9)/(x+8)
解方程x/(x-2)=2x/(x-3)+(1-x)/(x-5x+6)
解方程:(x-2)(x^2-6x-9)=x(x-5)(x-3)
方程:2X+4-x=9怎么解?还有X+6=4+3X.
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-2)X(x的平方-6x-9)=x(x-5)X(x-3)
解方程:2x+4x+6x...+100x=1-(x+3x+5x+...+99x)
解方程 x+2/x+1+x+8/x+7=x+6/x+5+x+4/x+3
7x(x-6)+3x=4x(2x+5)怎么解这个方程
解方程:2x(x-1)-x(3x+2)=-x(x+2)-12
解方程 (3x+1)(3x-1)=(x+2)(9x-4) 2(x-3)(x-2)-(x+3)²=(x-1)(x
