Math Problem Statement

∣4x−2∣−8=0

Solution

We are given the equation:

4x28=0|4x - 2| - 8 = 0

Step 1: Isolate the absolute value expression

Add 8 to both sides of the equation:

4x2=8|4x - 2| = 8

Step 2: Solve for the two cases

Since the absolute value of a number is always non-negative, the equation can be split into two possible cases:

Case 1: 4x2=84x - 2 = 8

Solve for xx: 4x=10(Add 2 to both sides)4x = 10 \quad (\text{Add 2 to both sides}) x=104=2.5x = \frac{10}{4} = 2.5

Case 2: 4x2=84x - 2 = -8

Solve for xx: 4x=6(Add 2 to both sides)4x = -6 \quad (\text{Add 2 to both sides}) x=64=1.5x = \frac{-6}{4} = -1.5

Step 3: Final solutions

The solutions are:

x=2.5orx=1.5x = 2.5 \quad \text{or} \quad x = -1.5
