Question

Help; what is 120 – 5x < 20

Answer 1

x>20

Explanation:

Hi there!

`120-5x < 20`

Subtract 120 from both sides

`120-5x -120< 20-120\\-5x<-100`

Divide both sides by -5 and switch around the inequality symbol (because we're dividing by a negative number)

`(-5x)/(-5) >(-100)/(-5) \\x>20`

I hope this helps!
