Math Problem Statement
Solve the equation for all values of x: |3x - 4| - 4 = 2x
Solution
The equation in the image is:
Let's solve this equation for all values of .
Step 1: Isolate the absolute value
Step 2: Handle the absolute value
Since the absolute value has two cases, we need to solve for both possibilities:
Case 1:
Case 2:
Step 3: Verify solutions
We need to check if both solutions satisfy the original equation.
- For : \quad \text{(True)}$$
- For : \quad \text{(True)}$$
Both solutions and are valid.
Final Answer:
The solutions are and .
