x =2.5(x-180)
x =2.5(x-180)
x =2.5(x-180)
x =2.5(x-180)
x=2.5x-450
2.5x-x=450
1.5x=450
x=300
x =2.5(x-180)
180=( )x( )x( )x( ) ×( )
180/x+180/(x-2.5)=360/(x-1.5)
x =2.5(x-180)解
(X+X)+(X-X)+(X*X)+(X/X)=100
180=( )x( )=( )X( )=( )X( )
x+x-2.5+x-4=85
2*x*x+2.5x=13 x=?
(x-2)+(x+2)+(x/2)+(2*x)=180
X乘X减2.5X=6, 求X!
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
2.5x-x=15
