Solve the inequality
Given inequality
⇒
Multiplying the inequality by 5.
⇒ -75 < 3(x – 2) ≤ 0
Dividing the inequality by 3 we get
⇒ -25 < x – 2 ≤ 0
⇒ – 25 + 2 < x – 2 + 2 ≤ 0 + 2
⇒ – 23 < x ≤ 2
∴ all real numbers x greater than -23 but less than or equal to 2 are solution of given equality.
x ∈ (-23, 2]
