6.8-0.25x=0.9,x=?
(X+X)+(X-X)+(X*X)+(X/X)=100
x-0.25=0.25x
x+x=x+15
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!)+.
求x 的值.x +3.5x =9.9;4.25x -x =4.55;10x -2.7x =58.4;6.8x +3.2x
INPUT "x=";x
解方程,帮帮忙,(X+0.9)+(X+0.09)+(X+0.009)+(X+0.0009)+(X+0.00009)=5.
x^5+x^4 = (x^3-x)(x^2+x+1)+x^2+x
X+X+X+X+X+X+100X=1690 问:X等于多少
10x-3.14*x*x*0.25=3.14*x*x*0.75 怎么算
已知 X=4- 根号3 求 (X*X*X*X-6X*X*X-2X*X+18X+23) / (X*X-8X+15)的值
(x-22)+(x-24)+(x-27)+(x-20)=x
