Answer: $5.5$

Explanation:

$1$ . Simplify the equation by treating the expression $(x - 3)$ as a single variable.

   - Let $A = x - 3$ . The equation becomes: $4A = 11 + 2A$.

$2$ . Solve the simplified equation for A:

   - Subtract $2A$ from both sides:

     $4A - 2A = 11$

     $2A = 11$

   - Divide by $2$ :

     $A = \dfrac{11}{2} = 5.5$ .

$3$ . Relate the result back to the original question:

   - Since we defined $A = x - 3$ , the value of $x - 3$ is $5.5$.

$4$ . Conclusion:

   - The value of $x - 3$ is $5.5$.
