Answer: $g>17$

Step-by-step explanation:

$-9g+11$

Move the g-terms to the left side. and the independent terms to the right side. Remember to change the sign if you move from one side to another.

$-9g+15g-7g$

$-16g+15g$

$-g$

Divide by -1 on both sides to make g positive. When it comes to dividing by negatives in inequalities, the inequality sign changes direction.

$\frac{-g}{-1}$

$g>17$
