b.

To solve the inequality , start by isolating . You can add 3 to both sides of the inequality, which gives you , simplifying to or in a more common format, . So, any value of that is less than -1 will satisfy the inequality!

It’s always a good idea to check your solution! Pick a value less than -1, say -2. Substitute it back into the original inequality: , which simplifies to – and that’s true! So, you’re on the right track.
