Equation Manipulation
Please manipulate these equations as specified, so that I can compare them to the other problems I need to do.

1. (w/v) = (g/(v-w)) to get 1/v + 1/w = 1/g
2. (w - g) = f²(1/(v-g)) into 1/v + 1/w = 1/g

I think you must have misunderstood the questions here. Are \$\displaystyle f\$ and \$\displaystyle g\$ functions? Give us the complete question please, because what you have written here doesn't make sense.

They are equations, not functions.

I am asking people to show the steps to rearrange (and manipulate) the equations.

How do I get from w/v = g/(v-w)
to 1/v + 1/w = 1/g ?

How do I get from w-g = f²(1/(v-g))
to 1/v + 1/w = 1/g ?

I have already replied to your question. Unless you have anything further to tell me, I repeat: the question doesn't make sense.
