The system has no solutions.
This is because it consists of two equations that their graphs represent parallel lines.So they have not a common point.
3x+y=9
6x+2y=4
We divide the second equation by 2
6x/2+2x/2=4/2
Simplify
3x+y=2
There is no pair of numbers (x,y) that makes these two equations
3x+y=9
3x+y=2
to come true in common.
So we obtain no solution.
