Solve the inequality 5x + 1 > – 24, 5x – 1 < 24 and represent the solution graphically on number line.
Given inequalities 5x + 1 > -24 and 5x – 1 < 24
5x + 1 > -24
⇒ 5x > -24 – 1
⇒ 5x > -25
⇒ x > -5 ………(I)
5x – 1 < 24
⇒ 5x < 24 + 1
⇒ 5x < 25
⇒ x < 5 ……….(II)
From (I) and (II) we conclude that solution of given inequalities is (-5, 5).
