So in this problem, we were given a situation.
00:03
We have that the two most common names for streets in the u .s.
00:07
Are second street, which i'll represent as an s, and then main street, which i'll represent as an m.
00:12
So totally in the u .s., there are 15 ,684 streets that have either one of this name, either one of these names.
00:19
So we have s plus m is going to be equivalent to 15 ,684, right? because we know that both of these names, that's how many streets there are having that name.
00:30
15 ,684 streets are the number of streets that have either second street or main street as their name.
00:39
Now we also know that there are 260 more streets named second street than main street.
00:45
So second street is going to be 260 more than main street.
00:52
So now we want to solve the systems of equation because that's how we set it up.
00:55
We can use the substitution method because we already isolate s.
00:59
So we have that...
