You're probably going to need to factorise

Collecting g terms on one side and factorising is usually the best way to go.

g - gh = 1 + 3h

g(1 - h) = 1 + 3h

g = \dfrac{1 + 3h}{1 - h}

g - 1 = gh + 3h
- 1 - 3h = gh - g
- 1 - 3h = g(h-1)
(Divide both sides by h -1)
- 1 - 3h/h-1 = g

Is this right?

-1=gh+3h-g
-1-3h=gh-g
-1-3h=g(h-1)
g=(-1-3h)/(h-1)

I know you've already got the answer, but I might as well practise for my maths exam tomorrow!

g-1=gh+3h
g=gh+3h+1
g-gh=3h+1
g(1-h)=3h+1

g = (3h+1)/(1-h)
