Transform equations

[cosmic jay]

I need to transform this equation to get R1. I know the result is R1 = 1/(1/Rges + 1/R2) but I don't know how to do it.
How do I get the the 1/ ... part?

1. Wait patiently for a helper to come along.
2. Once someone helps you, say thank you and close the thread with:

3. Feel free to nominate the person for helper of the week in #helper-nominations
4. Do not ping the mods, unless someone is breaking the rules.
5. If you're happy with the help you got here, and the server overall, you can contribute financially as well:

Are you sure it’s not -1/R2?

If so just subtract 1/R2 from each side then inverse each side

If a=b 1/a=1/b

no, it's as it says

Ok, solution:
|-1/R2
1/Rges - 1/R2 = 1/R1 | × R1
R1*(1/Regs - 1/R2) = 1 | / (1/Rges - 1/R2)
R1 = 1/(1/Rges - 1/R2)

@idle stone you were right, sorry for misubderstanding.
