x+180%x=3.2
x+180%x=3.2
(X+X)+(X-X)+(X*X)+(X/X)=100
x+x=x+15
求x 的值.x +3.5x =9.9;4.25x -x =4.55;10x -2.7x =58.4;6.8x +3.2x
解方程:1.x/x+1-1=3/(x+1)(x-2) 2.3/x+2+1/x=4/x²+2x 3.2/3+x/
36-(3x-10)=x-2x 3.2x=14.2-1.5x
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!)+.
解方程:3.2x=170%x+22.5 x=( )
x-2/5x=3.2 x=
90(x-180)=60(x+180) 求x
0.4x+3.2=2.5x+0.05 X是多少
120/x=180/1.2x x=?
