Question

please see image above. can someone please explain how this is correct? i don’t understand. tysm

Answer 1

-2/3x + 13 ≥ -1

Let's start off by subtracting 13 from both sides.

-2/3x ≥ -14

Divide both sides by -2/3. Dividing a negative number flips the sign.

x ≤ 21

The correct answers are 19, 20, and 21 because these numbers are less than or equal to 21.
