10x-6(8-x)=64
2x+(-6)=4x-8 (-2)x+10=3x+(-4)
解方程.(5x/x²+x-6)+(2x-5/x²-x-12)=7x-10/x²-6x+8
2x-10=15x+30,6x-6=6x+2,9-3x=2x-8,5x=9x-50 ,5y-5=12-6y,15x-9=
x+2/x+3-x+1/x+2=x+8/x+9-x+7/x+8
(x-6)/(x-5)-(x-7)/(x-6)=(x-9)/(x-8)-(x-10)/(x-9)
y=(x-1)(x-2)(x-3)(x-4)(x-5)(x-6)(x-7)(x-8)(x-9)(x-10)的导数在x=1
解方程:(x+8)/(x+7)+(x+10)/(x+9)=(x+7)/(x+6)+(x+11)/(x+10
设函数f(x)=(x-1)(x-2)(x-3)(x-4)(x-5)(x-6)(x-7)(x-8)(x-9)(x-10),
(x+7/x+6)+ (x+9/+x+8)=(x+10/x+9)+(x+6/x+5)
1.x+9/x+8- x+10/x+9=x+6/x+5- x+7/x+6;
⒈ 解方程 (X+7)/(X+6)+(X+9)/(X+8)=(X+10)/(X+9)+(X+6)/(X+5)
x-4/x-6+x-8/x-10=x-5/x-7+x-7/x-9
