(7X+6)-(2/3)*8X=14解方程
解方程:(x+3)/(x+2)-(x+5)/(x+4)=(x+7)/(x+6)-(x+9)/(x+8)
解方程 x+2/x+1+x+8/x+7=x+6/x+5+x+4/x+3
解分式方程 x-7/x-9+x-3/x-5=x-4/x-6+x-6/x-8
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-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
解方程:x/(x-2)+(x-9)/(x-7)=(x+1)/(x-1)+(x-8)/(x-6)
8x-3+2x+1=7x+6-5x 解方程
解方程x/(x-2)=2x/(x-3)+(1-x)/(x-5x+6)
