to solve for s you first have to isolate the term with the s in it. in order to get 9s isolated, I need to get rid of, or move, the 5g. to do this I add 5g to both sides.

9s=-4u+5g

I've isolated the term with the s in it, now I have to solve for s by dividing by its coefficient, 9.

s=(-4/9)u+(5/9)g

9s-5g=-4u

9s=5g-4u

s=(5g-4u)/9
