Question: How many solutions does the equation have? $|-6n| + 3 = 15$
1. **State the problem:** We need to find how many solutions the equation $$|-6n| + 3 = 15$$ has. 2. **Recall the absolute value property:** The absolute value of any number is always non-negative, so $$|-6n| = 6|n|$$ because absolute value removes the negative sign. 3. **Rewrite the equation:** $$6|n| + 3 = 15$$ 4. **Isolate the absolute value term:** $$6|n| = 15 - 3$$ $$6|n| = 12$$ 5. **Divide both sides by 6:** $$\cancel{6}|n| = \frac{12}{\cancel{6}}$$ $$|n| = 2$$ 6. **Solve the absolute value equation:** $$|n| = 2$$ means $$n = 2 \quad \text{or} \quad n = -2$$ 7. **Conclusion:** There are two solutions to the equation. **Final answer:** The equation has **two solutions**.
