180/x+180/(x-2.5)=360/(x-1.5)180/x+180/(x-2.5)=360/(x-1.5)180/x+180/(x-2.5)=360/(x-1.5)180/x+180/(x-
180/x+180/(x-2.5)=360/(x-1.5)
180/x+180/(x-2.5)=360/(x-1.5)
180/x+180/(x-2.5)=360/(x-1.5)
180/x+180/(x-2.5)=360/(x-1.5)
(180x-450)/(x²-2.5x)+180x/(x²-2.5x)=360/(x-1.5)
(360x-450)/(x²-2.5x)=360/(x-1.5)
360x²-540x-450x+675=360x²-900x
90x=675
x=7.5
x =2.5(x-180)
180=( )x( )x( )x( ) ×( )
(180x-36*x)/(x+2x)*2x=(180x-36*x)/(x+2x)*x+36x 这个怎么解啊····
180/x+180/(x-2.5)=360/(x-1.5)
X+(X+36)+(X-36)=180怎么解
(x-36)+(x＋36)+x=180
180=( )x( )=( )X( )=( )X( )
x =2.5(x-180)解
X+¼X=180
x+180%x=3.2
180-x/x=18%
(X-180)/X=0.3
x-0.2.x=180
x×5x=180
5X=180+X
(x-2)+(x+2)+(x/2)+(2*x)=180
初一求两个x的值 x+(x+10)+[180-(x+70)]=180x=?x+(x+20)+(x-10)+70+x=540x=?
直接写出X的值8x+4=32 (x+3)除以6=9 80-0.5x=25 38+2x=60 2.5x-2.5=7.5 2(1.2+x)=3.4 40x-0.9=3.1 9x-36=117 4.5x-x=3.5 0.5x+1.05=2x除以19+15=45 x除以94-45=55 12x+24x=12.6 3(x-30)=180 8x+25=1254.6x=9.2 5x-4.2=5.8一楼的 你的答案是很好
