Do the following equations represent a pair of coincident lines ? Justify your answer.
(i) `3x + (1)/(7)y = 3` and `7x + 3y = 7`
(ii) `-2x - 3y = 1 ` and ` 6y + 4x = -2`
(iii) `(x)/(2) + y + (2)/(5) = 0` and `4x + 8y + (5)/(16) = 0`

Explanation

To determine if the given equations represent a pair of coincident lines, we need to check the conditions for coincident lines. The equations are in the form \( a_1x + b_1y + c_1 = 0 \) and \( a_2x + b_2y + c_2 = 0 \). The lines are coincident if:

\[ \frac{a_1}{a_2} = \frac{b_1}{b_2} = \frac{c_1}{c_2} \]

Let's analyze each pair of equations one by one.
