X+1/0.2-2X=0.1x+0.2/0.03:
解方程:2- x+5/6=x- x-1/3,0.1-0.2x/0.03-1=0.7-x/0.4
化简(2x-5)(3x+2)-6(x+1)(x-2),其中x=0.2
(1)3x(x+0.2)=4x(x-1.1)
x-2/0.2-x+1/0.5=3 x=?
x/0.1-(x-1)/0.2=10
2- 6分之x+5=x- 3分之x-1 ,0.03分之0.1-0.2x-1=0.4分之0.7-x 怎么解方程!急
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
x+3/20x=46 ,x-1/5x=40 ,x-1/2x=3/4 ,x-0.2x=18解方程
x^5+x^4 = (x^3-x)(x^2+x+1)+x^2+x
x/x平方-x+2=2x/x+1
0.2x+0.5/0.5-0.03+0.02x/0.03=1 x-1/0.3-x+2/0.5=1
解方程:1+0.4x=0.2(x+10) 2.x÷2=x+200
