Description for Correct answer:
Given equations of system

3x + y = 4 ...(i)

6x + 2y = 8 ...(ii)

Here, \( \Large a_{1}=3, b_{1}=1, c_{1}=4, \)

\( \Large a_{2}=6, b_{2}=2, c_{2}=8 \)

Because, \( \Large \frac{a_{1}}{a_{2}}=\frac{b_{1}}{b_{2}}=\frac{c_{1}}{c_{2}}=\frac{1}{2} \)

So, the system of equations has infinite solutions, because it represents a parallel line.
