Solve the Absolute Value Equation: |2x - 4| = 8

Question

2x4=8 \left|2x - 4\right|=8

Step-by-Step Solution

To solve 2x4=8 \left|2x - 4\right|=8 , we split it into two cases based on the nature of absolute values:

1) 2x4=82x - 4=8:

Add 44 to both sides: 2x=122x=12.

Divide both sides by 22 to get x=6x=6.

2) 2x4=82x - 4=-8:

Add 44 to both sides: 2x=42x=-4.

Divide both sides by 22 to get x=2x=-2.

So, the solutions are x=2 x=-2 and x=6 x=6.

Answer

x=2 x=-2 , x=6 x=6
