Correct Answer: Option D
Explanation

Given:  
\(\frac{3 - y}{2x} = \frac{6y + 7}{4x - 5}\)

Substitute y = 2

\(\frac{3 - 2}{2x} = \frac{6(2) + 7}{4x - 5} \implies \frac{1}{2x} = \frac{19}{4x - 5}\)

Cross-multiply: 1 \(\cdot\) (4x - 5) = 19 \(\cdot\) 2x
4x - 5 = 38x
-5 = 38x - 4x
-5 = 34x

x = -\(\frac{5}{34}\)
