Math Problem Statement

|5 - 2x| = 4

Solution

The equation given in the image is:

52x=4|5 - 2x| = 4

To solve this absolute value equation, we will split it into two cases:

Case 1: Positive case

In the first case, we remove the absolute value and solve the equation directly: 52x=45 - 2x = 4 Subtract 5 from both sides: 2x=1-2x = -1 Now, divide both sides by -2: x=12=12x = \frac{-1}{-2} = \frac{1}{2}

Case 2: Negative case

In the second case, we negate the right side of the equation and solve: 52x=45 - 2x = -4 Subtract 5 from both sides: 2x=9-2x = -9 Now, divide both sides by -2: x=92=92x = \frac{-9}{-2} = \frac{9}{2}

Final Solution:

The solutions to the equation are: x=12orx=92x = \frac{1}{2} \quad \text{or} \quad x = \frac{9}{2}

  2. What happens if the right-hand side of the absolute value equation is negative?
  3. Can you explain how to solve inequalities involving absolute values?
  4. How does the absolute value function behave geometrically on a number line?
  5. Can absolute value equations have no solution?

Tip: Always check your solutions by substituting them back into the original equation, especially for more complex absolute value problems.
