Question: Gimme sum exercise like a student of computer science
1. **Problem Statement:**
Find the value of $x$ in the equation $$2x + 3 = 11$$.
2. **Formula and Rules:**
To solve a linear equation of the form $$ax + b = c$$, we isolate $x$ by performing inverse operations.
3. **Step-by-step Solution:**
1. Start with the equation:
$$2x + 3 = 11$$
2. Subtract 3 from both sides to isolate the term with $x$:
$$2x + 3 - 3 = 11 - 3$$
$$2x = 8$$
3. Divide both sides by 2 to solve for $x$:
$$\frac{\cancel{2}x}{\cancel{2}} = \frac{8}{2}$$
$$x = 4$$
4. **Answer:**
The value of $x$ is 4.
This is a basic algebraic exercise useful for computer science students to understand variable manipulation and equation solving.
