g must be greater than or equal to 15.
But there's one more thing in the > sign there is a line in the bottom
Apologies for the oversight. With the line underneath the "greater than" sign indicating "greater than or equal to", the solution set would be:

4g ≥ 6 x 10
4g ≥ 60
g ≥ 60/4
g ≥ 15

Therefore, the variable g must be greater than or equal to 15.
