The solution is $((x),(y))=((5),(2))$

We perform the Gauss Jordan elimination with the augmented matrix

$M=((3,4,:,23),(5,3,:,31))$

We perform the row operations

$R2larr3R2-5R1$ , $=>$ , $((3,4,:,23),(0,-11,:,-22))$

$R2larr(R2)/(-11)$ , $=>$ , $((3,4,:,23),(0,1,:,2))$

$R1larrR1-4R2$ , $=>$ , $((3,0,:,15),(0,1,:,2))$

$R1larr(R1)/(3)$ , $=>$ , $((1,0,:,5),(0,1,:,2))$
