do you have? A negative one is less than or equal to negative 1/2. And I'm just gonna divide by negative 1/2 on both sides. I wanna point out a couple things. We got two negatives that we're gonna be divided, so we'll get a positive. See, I can actually just cancel out those negatives. I divided both sides by a negative some any qualities going to switch directions and a divided by a fraction. So if using a calculator, please put it in parentheses. So one divided by half is to switch the direction canceled out. The number to get to is greater than n. And this is hard for some people. But to being bigger than end, um, people usually write their number there inequalities with the letter on the left. If two is bigger than an then and is smaller than two. So I can say anything smaller than to worse bracket because it's a greater than or equal to or less center equal to and then graphing it. Anything up to two works zero fill in the circle because of the less than or equal tuned
