    Nw to solve this inequality u hav to isolate x. To do that plz perform the following steps. 1.Add 9 to both sides. 2.Multiply both sides by 5. 3.Divide by -2 both sides. When u divide by a negative number the inequality sign flips. see if u can do it:)

    The last point of @ajprincess is very correct in inequality if we divide a negative number the inequality sign flips :)
