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
解分式方程:(x+1)/(x+2)+(x+6)/(x+7)=(x+2)/(x+3)+(x+5)/(x+6)
解分式方程: (x-1)/(x-2)+(x-6)/(x-7)=(x-2)/(x-3)+(x-5)/(x-6)
解方程:x/(x-2)+(x-9)/(x-7)=(x+1)/(x-1)+(x-8)/(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+2)/(x+1) - (x+4)/(x+3)=(x+6)/(x+5)-(x+8)/(x+7)
解方程x/(x-2)=2x/(x-3)+(1-x)/(x-5x+6)
解方程:7/x^2+x+3/x^2-x=6/x^2-1
解方程:7/x^2+x-6/x^2-1=3/x-x^2
解方程:7/x^2+x-2/x-x^3=6/x^2-1
解方程:2x(x-2)-6x(x-1)=4x(1-x)+16
解方程(x²-x+4)x-(x-1)(x²+2)=x+7
x/(x-2)+(x+1)/(x-6)=2x/(x-3) 解分式方程
方程(x+1)(x+2)(x+3)(x+4)(x+5)(x+6)(x+7)(x^2+8x+9)+64=01.不解方程是判断方程有几根2.解这个方程
1x+2x+3x+4x+5x+6x+7x+8x+9x+10x+11x+12x+13x+14x+15x=550必须用解方程
解方程(x+1)/(x+2)-(x+2)/(x+3)=1/9x+7)-1/(x+6)解方程(x+1)/(x+2)-(x+2)/(x+3)=1/(x+7)-1/(x+6)
7x(x-1)=2x+3解方程,
