Collect like terms, then it will be in a somewhat more familiar format.
I really don't know how to solve this system of equation, it's nothing I've ever done before.... mostly they would have identical and the same amount of variables in every column but this one doesn't....
x + 10 + y + 36 = 210
80 + 10 + z + y = 180
36 + z + y + t = 220
No, not like that. You have switched some additions to multiplications. Let's take the first one: x + 10 + y + 36 = 210 where we can subtract the 10 and the 36 from both sides to give x + y = 164. Follow that process with the other two and see where it takes you.
okay so t is equal to 94....
so can i take out the variable t out from the second and third equation and solve the second and third equation like a regular systems of equation?
Well this was my original question
Probability and Statistics homework problem question
Example 1: Computers, fine arts, economics - this one requires using system of equations
There are 500 seniors.
210 are enrolled in computers
80 do not need any of the 3
80 are taking only fine arts.
180 are taking fine arts.
36 taking only economics and computers
10 taking only fine arts and computers
220 taking economics
Find:
1.) P(only taking economics)
2.) P(economics and fine arts)
3.) P(taking all 3 classes)
Then this guy gave me this answer
(View the picture to understand how i got the system) So, you have
the system
1) x + 10 + y + 36 = 210
2) 80 + 10 + z + y = 180
3) 36 + z + y + t = 220
4) x + 10 + y + 36 + t + z + 80 = 420
