9. \( p+15=5 \)

To solve the equation \( p + 15 = 5 \), start by isolating the variable \( p \). You can do this by subtracting 15 from both sides, giving you \( p = 5 - 15 \), which simplifies to \( p = -10 \). Math magic! Now, if we think about situations where this can happen, consider budgeting scenarios where you’re in debt (like owing $15) and only have $5 left. Understanding this comforts you as you tackle real life situations or even manage finances—everyone can feel the pinch sometimes!
