∣5 x − 3∣ ≥ 7 5 x − 3 ≥ 7 ∨ 5 x − 3 ≤ − 7 5 x ≥ 10 ∨ 5 x ≤ − 4 x ≥ 2 ∨ x ≤ − 5 4 x ∈ ⟨ − 5 4 , 2 ⟩
To solve the inequality 7"> ∣5 x − 3∣ > 7 , break it into two cases: 7"> 5 x − 3 > 7 and 5 x − 3 < − 7 . Solving these yields 2"> x > 2 or x < − 5 4 , which can be expressed in interval notation as ( − ∞ , − 5 4 ) ∪ ( 2 , ∞ ) .
