All right, so in this problem, we have a stadium that seats 30 ,000 people.
00:05
We're told the home team gets four times as many tickets as the visiting team.
00:10
So we're going to let s equal the number of tickets the home team gets because i think it's spartans, san jose state.
00:30
Go saturday.
00:32
Sparty up.
00:33
Okay, so anyway, so the spartans get that.
00:35
That's why they call it s.
00:36
V is the number of tickets.
00:43
The visiting team gets.
00:48
It's always good to define the variables.
00:53
Okay.
00:54
So we know that the home team is going to be four times the visiting team.
01:02
Or if i said it equal to zero, s minus 4v equals zero.
01:08
Right? so we know that, you know, because if the visiting team gets one ticket, that means the home team gets four.
01:16
If the visiting team gets two tickets, the home team gets eight, four times two.
01:20
Okay.
01:21
Now, the other equation, right? so if i take how many tickets the home team has and add the number of tickets that the visiting team gets, v's the number of tickets that the visiting team gets, if i add those up, that has to equal 30 ,000.
01:47
Okay? now, because so if i put these two together, s plus 4v equals 30 ,000, if i put these two together, now that the s's are lined up, to solve this if i subtract straight down, or if i write s plus 4v equals 30 ,000, and i'm going to now subtract s minus 4v equals 0, if i'm going to now subtract s minus 4v equals 0, if i'm going to...
