Question 125919: Solve each compound inequality. Graph solutions set and write in interval notation.
x + 4 < 0 or 6x > -12

Okay, I just need to know where to start, because the rule is if there are two inequality signs separated by “or ” (as above) to solve for x in middle and the term “or” also means “union”. What I’m asking is what numbers do I begin with and how do I enter them? The first step to solving?
Thank you!
