Example 4 Solve (5 āˆ’ 2š‘„)/3 ≤ š‘„/6 āˆ’ 5. (5 āˆ’ 2š‘„)/3 ≤ š‘„/6 āˆ’ 5 (5 āˆ’ 2š‘„)/3 ≤ (š‘„ āˆ’ 30)/6 6 Ɨ (5 āˆ’ 2š‘„)/3 ≤ x – 30 2(5 – 2x) ≤ x – 30. 10 – 4x ≤ x – 30 – 4x – x ≤ – 30 – 10 – 5x ≤ – 40 – x ≤ (āˆ’40)/( 5) – x ≤ āˆ’8 Since x is negative, we multiply both sides by āˆ’1 & change the signs (– 1) Ɨ (–x) ≄ (– 1) Ɨ (–8) x ≄ 8 Hence, x is a real number greater than or equal to 8 Hence, x ∈ [8, āˆž) is the solution
