The given equation is:

$2 + \frac{3}{4}j + \frac{1}{2}j = 2j$

Here, the equation involves complex numbers with the imaginary unit $j$, where $j^2 = -1$.

Let's solve for $j$.

Step 1: Combine like terms

First, combine the terms involving $j$:

$\frac{3}{4}j + \frac{1}{2}j = 2j$

To add these, convert the fractions to a common denominator:

$\frac{3}{4}j + \frac{1}{2}j = \frac{3}{4}j + \frac{2}{4}j = \frac{5}{4}j$

Now, substitute this back into the equation:

$2 + \frac{5}{4}j = 2j$

Step 2: Isolate the imaginary terms

Move all terms involving $j$ to one side of the equation:

$\frac{5}{4}j - 2j = -2$

Convert $2j$ into a fraction with the same denominator:

$\frac{5}{4}j - \frac{8}{4}j = -2$

Now, subtract the fractions:

$\frac{-3}{4}j = -2$

Step 3: Solve for $j$

To isolate $j$, multiply both sides by $\frac{-4}{3}$:

$j = -2 \times \frac{-4}{3}$

Simplifying:

$j = \frac{8}{3}$

Thus, $j = \frac{8}{3}$.
