The correct Answer is:
To solve the inequality \( |2x - 3| < |x + 2| \), we will break it down step by step. ### Step 1: Understanding the Absolute Value Inequality The inequality \( |A| < |B| \) implies that \( A \) is less than \( B \) and also \( A \) is greater than \(-B\). Thus, we can write: 1. \( 2x - 3 < x + 2 \) 2. \( 2x - 3 > -(x + 2) \) ### Step 2: Solve the First Inequality Let's solve the first inequality: \[ 2x - 3 < x + 2 \] Subtract \( x \) from both sides: \[ 2x - x - 3 < 2 \] This simplifies to: \[ x - 3 < 2 \] Now, add 3 to both sides: \[ x < 5 \] ### Step 3: Solve the Second Inequality Now, let's solve the second inequality: \[ 2x - 3 > -(x + 2) \] Distributing the negative sign gives: \[ 2x - 3 > -x - 2 \] Now, add \( x \) to both sides: \[ 2x + x - 3 > -2 \] This simplifies to: \[ 3x - 3 > -2 \] Now, add 3 to both sides: \[ 3x > 1 \] Finally, divide by 3: \[ x > \frac{1}{3} \] ### Step 4: Combine the Results Now we have two inequalities: 1. \( x < 5 \) 2. \( x > \frac{1}{3} \) Combining these gives us: \[ \frac{1}{3} < x < 5 \] ### Final Solution The solution to the inequality \( |2x - 3| < |x + 2| \) is: \[ \boxed{\left(\frac{1}{3}, 5\right)} \]

To solve the inequality \( |2x - 3| < |x + 2| \), we will break it down step by step. ### Step 1: Understanding the Absolute Value Inequality The inequality \( |A| < |B| \) implies that \( A \) is less than \( B \) and also \( A \) is greater than \(-B\).
