Find the equation of straight line which passes through the intersection of the lines $3x-4y+1=0$ and $5x+y-1=0$ and $(2,1)$?

Question

$\begin{array}{1 1}(a)\;(3x-4y+1)-\large\frac{3}{10}\normalsize (5x+y-1)=0\\(b)\;(x-4y+1)-\large\frac{3}{13}\normalsize (5x+y-1)=0\\(c)\;(3x-2y+1)-\large\frac{4}{10}\normalsize (5x+y-1)=0\\(d)\;(x-y+1)-\large\frac{3}{10}\normalsize (5x+y+1)=0\end{array}$
