x-4/x-5 - x-5/x-6=x-7/x-8 - x-8/x-9求x=?
(x+7/x+6) +(x+9/x+8)=9x=(x+10/x+9) +(x+6/x+5)
x+2/x+1-x+4/x+3=x+6/x+5-x+8/x+7 x=?
(x+8)(x+6)(x+7)+(x+5)(x+6)(x+7)=(x+5)(x+8)(x+7)+(x+5)(x+8)(x+6)
1+x+x^2+x^3+x^4+x^5+x^6+x^7+x^8+x^9+x^10+x^11+x^12=97.8x+x^2+x^3+x^4+x^5+x^6+x^7+x^8+x^9+x^10+x^11+x^12=97.8 好多年没有用过过数学公式了 想不起来怎么算了 想知道 X值是多少
解分式方程：(x-4)/(x-5)+(x-8)/(x-9)=(x-7)/(x-8)+(x-5)/( x-6)
解方程:x-4/x-5 -x-5/x-6=x-7/x-8 -x-8/x-9
x-4/x-5-x-7/-x-8=x-5/x-6-x-8/x-9
解方程：(x-4)/(x-5)-(x-5)/(x-6)=(x-7)/(x-8)-(x-8)/(x-9)
解分式方程（X-4)/(X-5)-(X-5)/(X-6)=(X-7)/(X-8)-(X-8)/(X-9)
求方程解x-5/x-4+x-9/x-8=x-8/x-7+x-6/x-5
x-4／x-5-x-5／x-6=x-7／x-8-x-8／x-9求大神帮助
解因式方程：x-4/x-5+x-8/x-9=x-7/x-8+x-5/x-6
解方程(x-4)/(x-5)+(x-8)/(x-9)=(x-7)/(x-8)+(x-5)/(x-6)
(x-4)/(x-5) + (x-8)/(x-9)=(x-7)/(x-8) + (x-5)/(x-6)
