1x+2x+3x+4x+5x+6x+7x+8x+9x+10x+11x+12x+13x+14x+15x=550
解方程 x+2/x+1+x+8/x+7=x+6/x+5+x+4/x+3
解下列方程..1.(x/x-5)=(x-2)/(x-3)2.(6x-1)/(3x+2)=(4x-7)/(2x-5)3.{
解方程(x-2)/(x-3)-(x-3)/(x-4)=(x-5)/(x-6)-(x-6)/(x-7)
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
x-1\x-2+x-6\x-7=x-2\x-3+x-5\x-6 分式方程
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)
x+2x+3x+4x+5x+6x+7x+8x+9x=9x-8x-7x-6x-5x-4x-3x-2x-x.x等于多少?
(2x-1)/(x-1)(x-2)=(x-5)/(x-2)(x-3) x/2x^2-11x-21=(x+7)/x^2-1
