Okay, so here's a compound inequality to solve, and it's an or statement, so it's a union.
00:08
And what we're going to do is solve each inequality separately, and then find the union of their two solution sets.
00:14
To solve the first one, we'll subtract nine from both sides, and we get x is less than negative nine.
00:19
And to solve the second one, we'll divide both sides by four, so we get x is greater than negative three.
00:24
So x is less than negative nine or x is greater than negative three.
00:28
Let's picture that on a number line, just a rough sketch.
00:33
X is less than negative 9 looks like this.
00:36
X is greater than negative 3 looks like this.
00:39
Now we want all of that for a union...
