(80000-x)/(60000-x)=6得多少?
(80000-x)/(60000-x)=6得多少?
(80000-x)/(60000-x)=6得多少?
80000-x=360000-6x
5x=360000-80000
x=56000
x=56000
80000-x)/(60000-x)=6
80000-x=6(60000-x)
80000-x=360000-6x
5x=280000
x=56000
(80000-x)/(60000-x)=6
80000-x=6(60000-x)
80000-x=360000-6x
5x=280000
x=56000
x*x*x*x*x=80000?
（X+X)+(X-X)+(X*X)+(X/X)=100
(80000-x)/(60000-x)=6得多少?
x*x*x=504 x*x*x=504
（x+x）+(x-x)+(x/x)=11.2
f(x)=x,x
x+x=x+15
X(X-1)=X
180=( )x( )x( )x( ) ×( )
(x+30)*(x-18)=x*x
x+ x+(x*50%)=1.5X?
f(x)=x^2+x (x
用递归法求y=x-(x*x*x/3!)+(x*x*x*x*x/5!)-(x*x*x*x*x*x*x/7!)+.
80000/3=(x-200)(x-200),求x
