5x+【1000-x】*8=6932
x+2x+3x+4x+5x+6x+7x+8x+9x=9x-8x-7x-6x-5x-4x-3x-2x-x.x等于多少?
(x+12)(x-2)+(x+7)(x+8)-(x+5)(x-10),其中x=2
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=?
3x+5x=8x.
8x-5x=()x
8x(x-5)=3x
(x+8)(x+6)(x+7)+(x+5)(x+6)(x+7)=(x+5)(x+8)(x+7)+(x+5)(x+8)(x+6)

(5x-2)*(x+8)=5x*x+98
X/(X+1000)=5%
8x+3(x-2)=5x+(x-3)
X-5+8*X=7*X-2*X-1
(x-8)(x-5)=x*x-415
x-8/x-4=2-x-5/x-7
