SOLUTION: 2|2x-9|+4>6 how to solve? I got the answer (4,5) but that is incorrect. and on the graph technically it would go as like (4,oo), (5,oo) those were infinity's lol

You can put this solution on YOUR website! 2|2x-9|+4>6
subtract 4 from both sides of >
2|2x-9| > 2
divide both sides of > by 2
|2x-9| > 1
we have two cases to consider
***************************************
1) 2x-9 > 1
2x > 10
x > 5
2) -(2x-9) > 1
2x - 9 < -1
2x < 8
x < 4
****************************************
the solution is
x < 4 or x > 5
the intervals are
(-infinity, 4) or (5, +infinity)
