We are given the equation:

$3x + yi = 5x + 1 + 2i$

Step 1: Separate the real and imaginary parts.

• The real part is $3x$ on the left-hand side and $5x + 1$ on the right-hand side.
• The imaginary part is $yi$ on the left-hand side and $2i$ on the right-hand side.

Step 2: Equating the real and imaginary parts.

Real part:

$3x = 5x + 1$ Solving for $x$: $3x - 5x = 1 \implies -2x = 1 \implies x = -\frac{1}{2}$

Imaginary part:

$y = 2$

Final Solution:

$x = -\frac{1}{2}, \quad y = 2$
