8- 4/5 f > -14 - 2f     subtract 8 from both sides

- 4/5 f > -22 -2f          add 2f to both sides

 6/5 f >  -22                 multiply both sides by 5/6

f  > - 110/6

f > - 55/3

Set up the equation

 

\(8-\frac{4}{5}f>-14-2f\)

Now solve for f.

\(22>-\frac{6}{5}f\)

\(-\frac{55}{3}

 

Or for interval notation, \((-\frac{55}{3}, \infty)\)

 

You are very welcome!
