Solve the Absolute Value Equation: |3x - 5| = 4

Question

3x5=4 |3x - 5| = 4

Step-by-Step Solution

To solve this problem, we'll follow these steps:

  • Step 1: Consider the positive scenario: 3x5=4 3x - 5 = 4
  • Step 2: Consider the negative scenario: 3x5=4 3x - 5 = -4
  • Step 3: Solve each equation separately
  • Step 4: Identify the correct answer from the given choices

Let's work through each step:

Step 1: Solve 3x5=4 3x - 5 = 4 .
Add 5 to both sides: 3x5+5=4+5 3x - 5 + 5 = 4 + 5
So, 3x=9 3x = 9 .
Divide both sides by 3: x=93 x = \frac{9}{3} , thus x=3 x = 3 .

Step 2: Solve 3x5=4 3x - 5 = -4 .
Add 5 to both sides: 3x5+5=4+5 3x - 5 + 5 = -4 + 5
So, 3x=1 3x = 1 .
Divide both sides by 3: x=13 x = \frac{1}{3} .

Step 3: We have two solutions for x x , namely x=3 x = 3 and x=13 x = \frac{1}{3} .

Step 4: Comparing this with the given choices, the correct answer is "Answers b + c":

  • x=3 x = 3 corresponds to choice b.
  • x=13 x = \frac{1}{3} corresponds to choice c.

Therefore, the solution to the problem is Answers b + c.
