解方程1/(x+10)+1/(x+40)=1/(x-14),解方程1/(x+10)+1/(x+40)=1/(x-14),解方程1/(x+10)+1/(x+40)=1/(x-14),1/(x+10)+1
解方程1/(x+10)+1/(x+40)=1/(x-14),
解方程1/(x+10)+1/(x+40)=1/(x-14),
解方程1/(x+10)+1/(x+40)=1/(x-14),
1/(x+10)+1/(x+40)=1/(x-14)
1/(x+10)=1/(x-14)-1/(x+40)
1/(x+10)=-54/[(x+40)(x-14)]
(x+40)(x-14)=-54(x+10)
x²+26x-560=-54x-540
x²+80x-20=0
(x+40)²=1620
x+40=±9√20
x=-40±9√20
解方程(x/x(x+2))+(x/(x+2)(x+4))+.+x/(x+8)(x+10)=1
解方程:x-40%x+12=x-1/4
解方程;x-1/3x-40%x=100
1/x(x+1)+1/(x+1)(x+2)+...+1/(x+9)(x+10)=1/(x+10),解方程
解方程:(2x+5)(4x*x-10x+25)=8x(x*x+1)
解方程 x-1%x=19.8x-40%x=15x+25%x=2.550%x+x=31.5x-15%x=8.5
解方程1/(x+10)+1/(x+40)=1/(x-14),
解方程 (x+1)(500-10x)-40(500-10x)=8000
解方程x/(x-2)=2x/(x-3)+(1-x)/(x-5x+6)
1x+2x+3x+4x+5x+6x+7x+8x+9x+10x+11x+12x+13x+14x+15x=550必须用解方程
