Rearranging Formula

Make g the subject of g-1= gh+3h
can someone help me with this question s
thanks

You're probably going to need to factorise

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

Spoiler

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)

Thanks Guys !

yeah u are right ! :smile:

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