The equation $3 - \frac{2}{x} = \frac{4}{x}$ is a rational equation because it contains terms with variables in the denominator. Let's solve it step by step.

Steps:

1. Clear the fractions: Multiply both sides of the equation by $x$ (assuming $x \neq 0$) to eliminate the denominators:

   $x \left( 3 - \frac{2}{x} \right) = x \cdot \frac{4}{x}$

   This simplifies to:

   $3x - 2 = 4$

2. Solve the simplified linear equation: Add 2 to both sides to isolate the term with $x$:

   $3x = 6$

3. Divide by 3:

   $x = 2$

So, the solution to the equation is $x = 2$.

Check the solution:

Substitute $x = 2$ back into the original equation to verify:

$3 - \frac{2}{2} = \frac{4}{2}$ $3 - 1 = 2$ $2 = 2$

Since both sides are equal, the solution is correct.
