解方程:3.2x=170%x+22.5 x=( )
(X+X)+(X-X)+(X*X)+(X/X)=100
x+180%x=3.2
3.2x=170%x+22.5怎么解
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!)+.
x-2/5x=3.2 x=
0.4x+3.2=2.5x+0.05 X是多少
1.7x-120%x=6.5
