For a system of equations {ax+by+cz=jdx+ey+fz=kgx+hy+iz=l
, the coefficient matrix is [abcdefghi] and the augmented matrix is [abcjdefkghil]
a) For the system {9x3y+z=1312x8z=53x+4yz=6a=9,b=3,c=1,d=12,e=0,f=8,g=3,h=4andi=1 so the coefficient matrix is [9311208341]
b) For the system {9x3y+z=1312x8z=53x+4yz=6a=9,b=3,c=1,d=12,e=0,f=8,g=3,h=4,i=1,j=13,k=5andl=6 so the coefficient matrix is [9311208341] so the augmented matrix is [93113120853416]

Given the linear system of equations:
{ x 1 + x 2 + x 3 = n x 1 + x 2 + x 3 + x 4 + x 5 = 3 n 2 x 1 + 2 x 2 + 2 x 3 + x 4 + x 5 + 3 x 6 + 3 x 7 + 3 x 8 = 10 n
how many solutions are in N { 0 }?
The solution must not be using sum notation like y.
I know how to find the number of solutions to the regular equations like x 1 + x 2 + x 3 + = n but I'm not sure how to do this for a system of equations. I thought of substituting some x's:
x 1 + x 2 + x 3 = 3 n ( x 4 + x 5 ) x 4 + x 5 = 10 n 2 ( x 1 + x 2 + x 3 ) 3 ( x 6 + x 7 + x 8 ) x 1 + x 2 + x 3 = 3 n ( 10 n 2 ( x 1 + x 2 + x 3 ) 3 ( x 6 + x 7 + x 8 ) ) x 1 + x 2 + x 3 + 3 ( x 6 + x 7 + x 8 ) = 7 n
As far as I understand finding the number of solutions for the system is equivalent to finding the number of solutions to the equation *.
The only next step from here I can think of is using generating functions:
( 1 + x + x 2 + ) 3 ( 1 + x 3 + x 6 + x 9 + ) 3
and we need to find the coefficient of x 7 n .
From the closed form identities we have:
k = 0 ( 3 1 + k k ) x k i = 0 ( 3 1 + i i ) x 3 i
But I have no idea now how to find the coefficient of 7n from here and certainly not without using some kind of sum notation.
