百分数解方程40%x+21=372x+20%x=3.3
解方程:2x(x-1)-x(3x+2)=-x(x+2)-12
解方程(x²-x+4)x-(x-1)(x²+2)=x+7
解方程x/(x-2)=2x/(x-3)+(1-x)/(x-5x+6)
解方程:x/(x-2)+(x-9)/(x-7)=(x+1)/(x-1)+(x-8)/(x-6)
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+1+x+8/x+7=x+6/x+5+x+4/x+3
解方程(x/x(x+2))+(x/(x+2)(x+4))+.+x/(x+8)(x+10)=1
