x+2x+3x+4x+5x+6x+7x+8x+9x=9x-8x-7x-6x-5x-4x-3x-2x-x.x等于多少?
x-4/x-5 - x-5/x-6=x-7/x-8 - x-8/x-9求x=?
x+2/x+1-x+4/x+3=x+6/x+5-x+8/x+7 x=?
解方程(x/x(x+2))+(x/(x+2)(x+4))+.+x/(x+8)(x+10)=1
x(x+4)=8x+12
x(x+4)=8x+12
x(x-4)=2-8x
4,8-x=3x(x
1/(1-x)+1/(1+x)+2/(1+x*x)+4/(1+x*x*x*x)+8/(1-x*x*x*x*x*x*x*x)怎么做
(X+X)+(X-X)+(X*X)+(X/X)=100
6x+4x+8x=32 x=?
(x-3.6)/4=(x+4.8)/8x 求x
x-8/x-4=2-x-5/x-7
初二分式方程x+3/x+4+x+8/x+9=x+4/x+5+x+7/x+8解(x+3/x+4)+(x+8/x+9)=(x+4/x+5)+(x+7/x+8)
解方程】(x+8)/(x-3)-(x-9)/(x-4)=(x+7)/(x+8)-(x+2)/(x+3)(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)(x+8)/(x-3)-(x-9)/(x-4)=(x+7)/(x+8)-(x+2)/(x+3)
