帮帮我吧!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

原式:
8085975+77678xy-(xy-9843.63)
=8095818.63+77677xy
只能这样了
另请高明吧~

5/4x(9876x655)+77678xy=xy-8889.03-954.6的差,这道题目有答案吗? 谁会解这道题：(X-5)/(X-7)+(X-2)/(X-4)=(X-3)/(X-5)+(X-4)/(X-6)求X的值 计算[(x-1)/(x-2)-(x-2)(x-3)-(x-3)/(x-4)+(x-4)(x-5)]/(2x-7) 解因式方程：x-4/x-5+x-8/x-9=x-7/x-8+x-5/x-6 分解因式：x^4-6x^3-2x^2+18x+23/x^3-7x^2+5x+15 因式分解 3X^5+10X^4 - 15X^3 - 9X^2+8X+7 (x-4)(x-2)-(x-1)(x+3),其中x=-2/5 已知X/(X^2-X+1)=7,求X^2/(X^4+X^2+1)的值 求和：1/[(x+1)(x+2)]+1/[(x+2)(x+3)]+1/[(x+3)(x+4)]+1/[(x+4)(x+5)] 方程(x+1/x+2)+(x+2/x+3)=(x+3/x+4)+(x+4/x+5)的解
