Question: do a math problem
1. Let's solve a simple algebra problem: Solve for $x$ in the equation $$2x + 3 = 11$$.
2. The formula used here is to isolate $x$ by performing inverse operations.
3. First, subtract $3$ from both sides:
$$2x + 3 - 3 = 11 - 3$$
which simplifies to
$$2x = 8$$
4. Next, divide both sides by $2$ to solve for $x$:
$$\frac{2x}{\cancel{2}} = \frac{8}{\cancel{2}}$$
which simplifies to
$$x = 4$$
5. Therefore, the solution is $x = 4$.
