Question 743704: Hello,
I've been working on this problem for hours. This is my last hope of finding an answer. I hope you are able to solve this.
Solve the system of equations. (It's worth 10 points on my assignment)
x - 2y + 3z = 7
2x + y + z = 4
-3x + 2y - 2z = -10
The closest I have come to solving this system was: x = 0, y = 1, z = 3
When I was double checking the solutions,the top two equations checked out to work, but the last equation of the set of three didn't equal out. I don't know if this means that there is no solution, or if I have been doing it completely wrong.
If I could get an answer ASAP that would be amazing! Thank you in advance!!!

Question 743449: The income from a student production was $15750. if the price of a student ticket was $2 and the price of a non student ticket was $5 each and a total of 6000 tickets were sold, how many tickets of each kind were sold?
I tried using the substitution method to figure it out the final equation did not add up to the equations I used.
x+y=6000
2x+5y=15750
In the end I got
X=750
Y=5250
