Question: top-left: $12$\ntop-right: $9$\ncenter: $X + X = 24$\nUser: $X=?$
1. **State the problem:** We are given the equation $$X + X = 24$$ and need to find the value of $X$.
2. **Write the equation:** $$X + X = 24$$
3. **Combine like terms:** Since $X + X$ is the same as $2X$, rewrite the equation as:
$$2X = 24$$
4. **Solve for $X$:** Divide both sides of the equation by 2 to isolate $X$:
$$\frac{\cancel{2}X}{\cancel{2}} = \frac{24}{2}$$
5. **Simplify:**
$$X = 12$$
6. **Answer:** The value of $X$ is $12$.
