Question: User: $|x|+1=2$
1. **State the problem:** Solve the equation $$|x| + 1 = 2$$ for $x$. 2. **Understand the absolute value:** The absolute value $|x|$ represents the distance of $x$ from zero on the number line, so it is always non-negative. 3. **Isolate the absolute value:** Subtract 1 from both sides: $$|x| + 1 - 1 = 2 - 1$$ $$|x| = 1$$ 4. **Solve the absolute value equation:** The equation $|x| = 1$ means $x$ can be either 1 or -1. 5. **Write the solution:** $$x = 1 \quad \text{or} \quad x = -1$$ **Final answer:** $x = \pm 1$
