2x + y = 3 \\ 2x + y - 3 = 0 \:.............(1) \\ 4x + 2y = 6 \\ 4x + 2y - 6 = 0.............(2)

eq (1) & (2) are in the form of quadratic equation

now \\ a1 = 2 \\b1 = 1 \\ c1 =  - 3 \\  a2 = 4 \\ b2 = 2 \\ c2 =  - 6

 \frac{a1}{a2}  =  \frac{2}{4}  =  \frac{1}{2}

 \frac{b1}{b2}  =  \frac{1}{2}

 \frac{c1}{c2}  =  \frac{ - 3}{ - 6}  =  \frac{1}{2}

Therefore, the lines represented by the eq (1) and (2) are co-incident.
