Question

谁给我15道分数一元一次方程 例如3x+2/2-1=2x+1/4-2x-1/5这样的题带答案,

Answer 1

1.(4x+2)/6-(5x-1)/6

-x+3=6x=-3

2.4x/(2x+6)+1=7/(2x+6)

7-4x=2x+6

x=1/6

3.0.4(x-0.2)+1.5=0.7x-0.38

x=6

4.30x-10(10-x)=100

x=5

5.4(x+2)=5(x-2)

x=18

6.120-4(x+5)=25

x=18.75

7.15x+863-65x=54

x=16.18

8.3(x-2)+1=x-(2x-1)

x=3/2

9.11x+64-2x=100-9x

x=2

10.3X+18=52

x=34/3

11.4Y+11=22

y=11/4

12.3X*9=5

x=5/27

13.8Z/6=48

z=36

14.8X*6=5

x=5/48

15.5-6=5x

x=-1/5

16.6*x=42

x=7

17.11*3x=60

x=20/11

18 .3X+5X=48

X=6

19.14X-8X=12

X=2

20.10X*（5+1）=60

X=1
