I have but it doesn't say about how to make g the subject it mentions v which is no good to me, its the last question I know u have to do the same to both sides

Ok, so you already have some understanding of doing same to both sides. And that you need to get 3g on its own first (as we're making g the subject).

x = 3g + 2
we first need to take away two from both sides
x (-2) = 3g +2 (-2)
what is this?

Yes, I corrected my mistake.

Here is an example of a similar question and the solution.

Okay, let me see if I can help.

The question is x = 3g + 2: Rearrange for g.

Firstly:
-2 from both sides of the equation so that you get x-2 = 3g
Secondly:
Divide 3 from both sides. In this circumstance x-2 is really (x-2). And should be taken as a packet.

Answer:

g = (x-2)/3
