Misc 5 Solve the inequality β12 < 4 β3π₯/(β5) β€ 2 β12 < 4 β3π₯/(β5) β€ 2 Subtracting 4 all sides (Eliminating 4) β 12 β 4 < 4 β 3π₯/(β5) β 4 β€ 2 β 4 β16 < β3π₯/(β5) β€ β2 β16 < 3π₯/5 β€ β2 Multiplying 5 all sides (Eliminating 4) β16 Γ 5 < 3π₯/5 Γ 5 β€ β2 Γ 5 β80 < 3x β€ β10 Dividing 3 all sides (Eliminating 3) (β80)/3 < 3π₯/3 β€ (β10)/3 (β80)/3 < π₯ β€ (β10)/3 Thus, x is a real number which is less than or equal to (β10)/3 and greater than (β80)/3 Hence, x β ((βππ)/π,(βππ)/π] is the solution
