If \( 4x + i(3x - y) = 3 + i(-6) \), where \( x \) and \( y \) are real numbers, the value of \( y \) is:

  1. A
    \( \frac{33}{4} \)
  2. B
    \( \frac{3}{4} \)
  3. C
    \( -\frac{33}{4} \)
  4. D
    \( -\frac{3}{4} \)
View Answer & Solution

Correct answer · Option A

\( \frac{33}{4} \)

Explanation

Equating real parts gives \( 4x = 3 \implies x = \frac{3}{4} \). Equating imaginary parts gives \( 3x - y = -6 \implies 3(\frac{3}{4}) - y = -6 \implies y = \frac{9}{4} + 6 = \frac{33}{4} \).
