0.1x-0.3/0.02-x+1/0.5=1
(0.1X-0.02)/0.01-(X+1)/0.5=3
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.
解方程0.3x+0.8/0.5-0.02x+0.3/0.3-1=0.8x-0.4/3
解方乘(1-0.5x)/0.3-( 2x-1)/3=0.3x/0.02
(0.1x-0.2)/0.02+(x+1)/0.5=3 求x
1-0.5x/0.3-2/3x=0.3x/0.2x+1
0.1x-3\0.2+0.3x+0.5\0.6=x-1\3
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
(3x-1)/0.5=(4-x)/0.3+(3x+5)/1.5 x得多少?
x^5+x^4 = (x^3-x)(x^2+x+1)+x^2+x
1、0.3X-0.4X=0.5 2、5X-2.5X+3.5X=-18 3、X-2/5X=-3+6
