All right, so once again, i'm going to do this in two steps, which might be different than the way that you would solve this.
00:07
I notice that 16 and 28 both share a greatest common factor of 4.
00:13
And so i'm going to divide both sides by 4 to begin with.
00:19
Most people would divide by 16 first, then they would simplify from there.
00:23
I like to do the simplifying first in this case.
00:25
It makes it a little bit easier.
00:27
So this is 4 times m is less than negative 7.
00:33
Now i'm going to divide by the rest, and then i'll just have my answer.
00:39
So m is less than negative seven -fourths, or negative one and three -fourths.
00:49
And that gives us our set notation.
00:51
We want all the m values such that m is less than negative seven -fourths.
00:59
So then when we graph, let's put zero a little bit further to the right, and we'll go four spaces, and that will be negative 1, four more spaces, and that will be negative 2...
