Math Problem Statement

|3x - 5| - 6 = 4

Solution

To solve the equation:

3x56=4|3x - 5| - 6 = 4

  1. Isolate the absolute value term by adding 6 to both sides: 3x5=10|3x - 5| = 10

  2. Set up two separate equations because the expression inside the absolute value can be either positive or negative: 3x5=10or3x5=103x - 5 = 10 \quad \text{or} \quad 3x - 5 = -10

  3. Solve each equation separately:

    • For 3x5=103x - 5 = 10: 3x=153x = 15 x=5x = 5

    • For 3x5=103x - 5 = -10: 3x=53x = -5 x=53x = -\frac{5}{3}

  4. Final solution: x=5orx=53x = 5 \quad \text{or} \quad x = -\frac{5}{3}

So, the values of xx that satisfy the equation are:

x=5orx=53x = 5 \quad \text{or} \quad x = -\frac{5}{3}

  1. What is the solution if the absolute value equation were 3x5+6=4|3x - 5| + 6 = 4?
  2. How would the solution change if we had 3x5=10x|3x - 5| = 10x?
  3. What are the steps to solve 2x+4=8|2x + 4| = 8?
  4. Can absolute value equations have no solutions? If so, under what conditions?
  5. How do you solve absolute value inequalities, like 2x1<5|2x - 1| < 5?

Tip: When solving absolute value equations, always isolate the absolute value expression before setting up separate equations.
