Answer

\( p < -q \)

Solution

It looks like you're working with the inequality: \[ 2p < p - q \] Let's solve this inequality step by step. You can solve for either \( p \) or \( q \). Below are both approaches: ### Solving for \( p \): 1. **Start with the original inequality:** \[ 2p < p - q \] 2. **Subtract \( p \) from both sides to isolate terms containing \( p \):** \[ 2p - p < -q \] \[ p < -q \] **Solution:** \[ p < -q \] ### Solving for \( q \): 1. **Start with the original inequality:** \[ 2p < p - q \] 2. **Subtract \( p \) from both sides to move \( p \) to one side:** \[ 2p - p < -q \] \[ p < -q \] 3. **Multiply both sides by \( -1 \) to solve for \( q \). Remember that multiplying or dividing both sides of an inequality by a negative number reverses the inequality sign:** \[ -p > q \] \[ q < -p \] **Solution:** \[ q < -p \] ### Summary - **Solving for \( p \):** \[ p < -q \] - **Solving for \( q \):** \[ q < -p \] **Interpretation:** The inequality establishes a relationship between \( p \) and \( q \), indicating that \( p \) must be less than the negative of \( q \), and vice versa. If you have any further questions or need additional clarification, feel free to ask!

Bonus Knowledge

To solve the inequality \( 2p < p - q \), first, let's rearrange it by subtracting \( p \) from both sides. This gives us \( 2p - p < -q \), which simplifies to \( p < -q \). This tells us that \( p \) must be less than the opposite of \( q \). This relationship helps us understand how values of \( p \) and \( q \) can interact, especially in problems involving constraints and inequalities. Furthermore, in real-world applications, such inequalities might represent resource management scenarios. For instance, if \( p \) stands for the production capacity of a factory and \( q \) represents the demand from consumers, ensuring \( p < -q \) can indicate that production isn't meeting demand, necessitating adjustments in resources or output to better align with market needs.
