.
Notice that if x is negative, then 6%2Fx is negative and, therefore, can not be greater or equal to 5.


Hence, the solution set {x} is among positive real numbers.


Assuming that x is positive, multiply both sides of 6%2Fx >=5 by x.

Since x is positive, you can keep the same inequality sign.


So, your inequality becomes 6 >= 5x.


Now divide both sides by the positive number 5. You will get an equivalent inequality  x <= 6%2F5.

Answer. The solution set is 0 < x <= 6%2F5.

Illustration:


graph%28+330%2C+330%2C+-5.5%2C+5.5%2C+-5.5%2C+10.5%2C%0D%0A++++++++++6%2Fx%2C+5%0D%0A%29

Plots y = 6%2Fx (red) and y = 5 (green)
