|2x - 4| > 2
Rewrite the inequality as:
-2 > 2x - 4 > 2
So:
2x - 4 > 2 (1)
2x - 4 < -2 (2)
Solving for (1)
2x - 4 > 2
Add 4 to both sides:
2x -4 + 4 > 2 + 4
2x > 6
Divide both sides by 2:
2x/2 > 6/2
x > 3
Solving for (2)
2x - 4 < -2
Add 4 to both sides:
2x - 4 + 4 < -2 + 4
2x < 2
Divide both sides by 2:
2x/2 < 2/2
x < 1
Therefore, the solutions are:
x > 3 or x < 1
