I have a page full of questions for my physics class and I've forgotten the basic steps to rearranging formulas. Here are 2 examples of the types of questions I have on my sheet.

2. Relevant equations

Solve the equation y=mx+b for m.

Solve the equation F=GMm/r^2 for m.

3. The attempt at a solution

I tried to remember what to do, and I know it has something to do with doing what you do to one side to the other. So for the first one I just put -x-b+y=m and im pretty sure it's terribly wrong. For the second i played around and tried m=GM/Fr^2 which I'm also sure is pretty wrong.

I can't find a topic in my text to tell me how to do these operations as its expected that I already know them. IS there an online tool with these rules anywhere? Can you help me figure these two out? I think knowing these I can do the rest.
