50/(x+4)+1<4x

**Steve**, Saturday, November 12, 2011 at 11:36pmIf x+4 > 0, we can multiply and not change the direction of the inequality:

4x^2 + 15x -54 > 0

(4x-9)(x+6) > 0

for x > 9/4 that is true

If x+4 < 0, e change the direction of the inequality, and have

(4x-9)(x+6) < 0

Unfortunately, whe have no values for x that satisfy the condition and the inequality.

So, x in (9/4,oo) is the only interval
