Solution:

Simplify the inequality one by one:

  • -10 ≤ 5 + x < -5
  • => -10 - 5 ≤ x
  • => -15 ≤ x
  • => 5 + x < -5
  • => x < -5 - 5
  • => x < -10

This means that...

  • -15 ≤ x < -10

Hoped this helped!

Required solution :

First solving for -10 < 5 + x

⇒-10 - 5 < x

⇒ -15 < x

Now for 5 + x < -5

⇒ x < -5 - 5

⇒ x < -10

Therefore,

  • -15 < x < -10
