This problem is talking about the number of refugees from africa and near east south asia.
00:07
The total was 49 ,087, and the number from near east, south asia was 4 ,313 less than three times the number from africa.
00:19
And we're asked to determine the number of refugees from each location.
00:24
So first we'll identify our variables.
00:26
I'll let a equal the number of refugees from africa.
00:43
And i will use n.
00:46
I'm sorry, i should be using lowercase, to equal the number of refugees from near east, south africa.
01:05
Or south asia, my apologies.
01:13
First sentence tells us a total amount.
01:16
So that means a plus n, will be equal to 49 ,087.
01:24
And then the near east south asia is 4 ,313 less than.
01:34
So we're going to be subtracting that from three times the amount of africa.
01:42
This setup, because we're told that n equals, and then we have an expression, that signifies that substitution would be best to use...
