0.1x/0.2%0.01x%0.01/0.06=x%1/3怎么算

原式即:x/2 -x/100 - 1/6 =x -1/3 x - 50x/100 + x/100=1/3-1/6 51x/100=1/6 x=50/153

(x+1)/0.2-(x+3)/0.01=3 5(x+1)-100(x+3)=3 5x+5-100x-300=3 5x-100x=300+3-5 -95x=298 x=298÷(-95) x=-398/95 不懂可追问,有帮助请采纳,谢谢!

0.1-1/10-x+2=3 0.1-0.1-x+2=3 -x=1 x=-1

解: (1-3/5)*6=1/2x (1-0.6)*6=0.5x 0.4x6=0.5x 0.5x=2.4 x=4.8

x–1/0.3–x+2/0.2=10 解:x-10/3-x+20/2=10

0.1x+0.2/0.3—2x+1/0.2=3 0.1x+2/3—2x+10/2=3 0.6x+4-12x+30=18 16=11.4x x=16/11.4=160/114=80/57

0.5x-1/0.2-0.1x+2/0.3=-1 0.6x-5+20/3=-1 0.6x=-1+5-20/3 0.6x=-8/3 x=-40/9

x-3/2+2=0.1x+10/3☞2x-3/2=0.1x+10/3☞1.9=29/6☞x²=145/57☞x=√145/57

这题的难点在于x=1处不连续,由分布函数,F(1)=0.5 而x=1处的左极限F(1-)=1/3,其他连续处F(t)=F(t-) P{X
