One-dimensional linear equation:

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

2. 1 1x+64-2x = 100-9x

3. 15-(8-5 times) = 7 times +(4-3 times)

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

8.30 x- 10( 10-x)= 100

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

10. 120-4(x+5)=25

1 1. 15x+863-65x = 54

12. 12.3(x-2)+ 1 = x-(2x- 1)
