Answer 2

${ \underline{ \boxed{ \sf{ \large{ \color{red}{Given \: inequation,}} }}}}$

30 – 4 (2x – 1) < 30

30 – 8x + 4 < 30

34 – 8x < 30

-8x < 30 – 34

-8x < -4

[On multiplying both sides by -1, the inequality reverses]

8x > 4

x > 4/8

⇒ x > 1/2

As x is a positive integer

The solution set is {1, 2, 3, … }
