Math Problem Statement

solve for \left|2x-4\right|=10

Solution

To solve the equation 2x4=10|2x - 4| = 10, we need to break it into two cases, as the absolute value can result in either a positive or negative expression.

Case 1: 2x4=102x - 4 = 10

2x4=102x - 4 = 10 Add 4 to both sides: 2x=142x = 14 Now divide by 2: x=7x = 7

Case 2: 2x4=102x - 4 = -10

2x4=102x - 4 = -10 Add 4 to both sides: 2x=62x = -6 Now divide by 2: x=3x = -3

Final Answer:

The solutions are x=7x = 7 and x=3x = -3.
