Question

Solve the inequality:
-5x + 18 < -12

Answer 1

Explanation:

-5x + 18 < -12

subtract 18 from both sides:

-5x + 18 - 18 < -12 - 18

-5x < -30

divide both sides by -5: [remember, when dividing by a negative number you must FLIP the sign direction]

(-5x)/-5 > (-30)/-5

x > 6

or

(6 , ∞)
