# Calculation of rank of a matrix

If $A=(a_{ij})$ is a ${n \times n}$ matrix such that $\forall i,j$ ,$a_{ij}=2i+3j$ then what is the rank of $A$?

I tried this problem but I'm getting nowhere. Is there any direct (or indirect) method to calculate the rank of $A$? Any help will be appreciated. Thanks and regards.
