Rozwiąż dwie nierówności :
x - [ 3*(x - 1)]/ 6 > 3 x + 5 1/2 / * 6
6 x - 3*( x - 1) > 18 x + 33
6 x - 3 x + 3 > 18 x + 33
3 x - 18 x > 33 - 3
- 15 x > 30 / * ( - 15)
x < - 2
=========
2 x + 3*( 1 - 2 x) > = ( 8 x + 14 )/ 4 / * 4
8 x + 12*( 1 - 2 x) > = 8 x + 14
8 x + 12 - 24 x > = 8 x + 14
- 24 x > = 14 - 12
-24 x > = 2 / :( - 24)
x < = - 1/12
