X-[(X-3500)*0.25-1005]=10000
X-[(X-3500)*0.25-1005]=10000
X-(X-3500)*0.25-1005=13636.4 方程怎么解
x+(x*0.0683)=3500 x=?
(X+X)+(X-X)+(X*X)+(X/X)=100
x-0.25=0.25x
x+x=x+15
10x-3.14*x*x*0.25=3.14*x*x*0.75 怎么算
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!)+.
X-{[(X-430.5-3500)*0.2-555]+430.5}=10000,X等于多少
x-[(x-3500)*0.2-555]=9553求x=?
(X-10000)/(X/0.17)=0.1,求X,
16+0.2x=0.25x十9求x!
