1. **State the problem:** Solve the equation $x + x = y$ for $x$. 2. **Understand the equation:** The equation $x + x = y$ means adding $x$ to itself equals $y$. 3. **Use algebraic rules:** Combine like terms on the left side: $x + x = 2x$. 4. **Rewrite the equation:** Now we have $2x = y$. 5. **Solve for $x$:** Divide both sides by 2 to isolate $x$: $$x = \frac{y}{2}$$ 6. **Interpretation:** The value of $x$ is half of $y$. This means if you know $y$, you can find $x$ by dividing $y$ by 2. **Final answer:** $$x = \frac{y}{2}$$
