So lets try and write it mathematically. 

5f+8 ≥ 2+6f

Lets try and put the numbers on one side and the variables on the other side of this inequality. Every variable or number that will change its side, it will have its sign changed from a + into a - and vice versa. The inequality sign wont be affected from this switch.

5f-6f ≥ 2-8

-f ≥-6

Lets divide both sides with -1. Since we are dividing both sides with a negative number, that will change the sign of the inequality and will flip it.

-f/(-1) ≥ -6/(-1)

f ≤ 6
