Math Problem Statement

Solve the absolute value equation. |2x - 3| = 7

Solution

To solve the absolute value equation 2x3=7|2x - 3| = 7, follow these steps:

Step 1: Split the absolute value equation

The absolute value equation A=B|A| = B implies two cases:

  1. A=BA = B
  2. A=BA = -B

For 2x3=7|2x - 3| = 7, we set up the two cases:

  1. 2x3=72x - 3 = 7
  2. 2x3=72x - 3 = -7

Step 2: Solve each equation

Case 1: 2x3=72x - 3 = 7

Add 3 to both sides: 2x=102x = 10

Divide by 2: x=5x = 5

Case 2: 2x3=72x - 3 = -7

Add 3 to both sides: 2x=42x = -4

Divide by 2: x=2x = -2


Step 3: Combine the solutions

The solution to the equation 2x3=7|2x - 3| = 7 is: x=5orx=2x = 5 \quad \text{or} \quad x = -2
