Hey there!

I'd like to giveaway my TM Payday for help on a math problem!

To win the prize, I need an answer and work shown.
I don't care what process you use, as long as it gets a correct answer.

Here is the problem.

2m + 3n - p + q + 2r - s + 2t = 1
m - n + p - q + r + s + t = 2
2m + 2n -2p + q - 2r + s - t = 1
m - 2p + q - r - s + t = 1
m - 2n + p -q + r + s + t = 2
m + 2n + 2p + 2q + r -s + 2t = 1
m - n - 2p - q - r + s + t = 2

I need a value for every single variable, no solution is a potential answer.
Thanks!

Using Gauss-Jordan Elimination, this is what I got:
m = 5/4
n = 0
p = 1/2
q = -1
r = -3/4
s = -1/2
t = 1/2

Solution (huge image):
Spoiler: show

My dad is working on it :3
I think he's going to leave it for tomorrow when he come back from work...
I guess the prize belongs to Bryan... But it's always nice to see your dad working hard XD
And two ways of solving is always better then just one.

I think he gave up on this problem...
