The system is indeterminate. THe two lines are parallel, and do not have a solution. Rearrange the second equation to
3x+y=9 Which is the same x,y coefficents as the first equation.
Solving a system of equations means finding the intersection of the two lines.
Your 2 equations represent two parallel lines, they cannot intersect, therefore you cannot have a solution.
