Math Problem Statement

Solve each equation and graph the solution set for absolute value equations.

Solution

The image shows a series of exercises involving solving absolute value equations and graphing the solution sets on a number line. Here's an overview of how to approach these types of problems:

For Absolute Value Equations:

  1. General Rule:
    • If xa=b|x - a| = b, this means xa=bx - a = b or xa=bx - a = -b.
    • Solve both equations to find the values of xx.

Example Breakdown of Solutions:

  1. Problem 1:

    • x3=5|x - 3| = 5
      • x3=5x - 3 = 5x=8x = 8
      • x3=5x - 3 = -5x=2x = -2
    • Graph: A number line showing two points: x=2x = -2 and x=8x = 8.
  2. Problem 2:

    • x+4=9|x + 4| = 9
      • x+4=9x + 4 = 9x=5x = 5
      • x+4=9x + 4 = -9x=13x = -13
    • Graph: Points at x=13x = -13 and x=5x = 5.

Each problem follows a similar pattern where you isolate the absolute value, split it into two equations, and solve both.

Would you like me to provide a step-by-step solution for each equation or assist with specific questions? Also, here are 5 related questions for practice:

  1. How do you solve x2=7|x - 2| = 7?
  2. What is the general process for graphing solutions on a number line?
  3. How would the equation 2x+3=8|2x + 3| = 8 be solved?
  4. What happens if the right-hand side of an absolute value equation is negative, such as x1=3|x - 1| = -3?
  5. How can you write an absolute value equation given a number line with solution points?

Tip: Always check if the equation has a real solution. If the absolute value equals a negative number, there are no solutions.
