0.5/0.2x+0.5=4+0.03/0.03+0.02x
0.5/0.2x+0.5=4+0.03/0.03+0.02x
(2x+5)/5=4+(3+2x)/3
3(2x+5)=60+5(3+2x)
6x+15=60+15+10x
-4x=60
∴x=-15

求x:|x|-|x-4|=0.5x-1
4x一5/0.5—5x-0.8/0.2=1.2-x/0.1 x=
方程(1)x-3/4(x-2)=1/2[x-1/3(x-2)] (2) 0.02x-0.01/0.03-0.4x+0.2/0.5+3x+2/4=1 一定要对,
解方程.(0.5x+2)/0.03-x=[0.3(0.5x+2)]/0.2解方程.(0.5x+2)/0.03-x=[0.3(0.5x+2)]/0.2
0.2x+0.5/0.5--0.03+0.12x/0.3=x-6/2(0.2x+0.5)/0.5-(0.03+0.12x)/0.3=(x-6)/2
(X+4)/0.2-(X-3)/0.5=0.2 x-(x-1)/6=3-(x+2)/3 x/12-(2x-1)/20={(3x+4)/8}-1 2%x-5+5%x=20%0.13(x-1)=0.07(x+1) x/2-x/6+x/8-x/10=1-1/3+1/4-1/5
x / 2 - 5x+11 / 6 =1 + 2x-4 / 30.1x-0.2 / 0.02 - x+1 / 0.5 = -3
3.2+x=4.6 x-2.08=5.76 1.2x=0.84 3x+0.5x=4.2 4x-2.16=1.2 x-0.2x=16 2x-4*2.5=3.6 x除以5.4=0.26
3x+0.5x=4.2 4x-2.16=1.2 x-0.2x=16 2x-4x[这个x是乘】2.5=3.6 3x+5x=168 怎么解
