1.2(x-2)-3(4x-1)=9(1-x)

2.11x+64-2x=100-9x

3.15-(8-5x)=7x+(4-3x)

4.3(x-7)-2[9-4(2-x)]=22

5.3/2[2/3(1/4x-1)-2]-x=2

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

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

8.30x-10(10-x)=100

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

10.120-4(x+5)=25

11.15x+863-65x=54

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

13.11x+64-2x=100-9x

14.14.59+x-25.31=0

15.x-48.32+78.51=80

16.820-16x=45.5×8

17.(x-6)×7=2x

18.3x+x=18

19.0.8+3.2=7.2

20.12.5-3x=6.5
