(0.05-0.2x)/0.02=1+x/0.5
(0.1x-0.2)/0.02+(x+1)/0.5=3 求x
先化简再求值先化简再求值:(x-x/x+1)(x+1/x^2+4x+4)(x^2-4/x^2-2x),其中x=-0.5
若1+x+x*x+x*x*x=0,求x+x*x+x*x*x+.+x(2000次幂)
x-2/0.2-x+1/0.5=3 x=?
(x/x-1)+(5x-2)/x*x-x=1 求x(有图)
求1/2x^2-1/4x+0.2x^3+0.25x-0.5x^2-1/5x^3+0.5x-1 其中x=12/13
0.2x+0.5/0.5-0.03+0.02x/0.03=1 x-1/0.3-x+2/0.5=1
0.3分之1-0.5x减0.3分之0.2x-1=0.02分之0.3x.
(1)3x(x+0.2)=4x(x-1.1)
(1)1-x/3=8-2x/2[解方程][过程要有] (2)0.1x-0.2/0.02=3+x+1/0.5[解方程][过
(1) x-3/x-2 - x-5/x-4=x-7/x-6 - x-9/x-8
3/x-1=4/x 6/x+1=x+5/x(x+1)
