Do you not know basic algebra? You should have learned how to do this in 8th grade.

Although Ian has given the answer he did not show how to work it out.
P= (Vs-1.683) / 0.131

P = Vs/0.131 - 1.683/0.131

Vs/0.131 = P + 1.683/0.131

Now multiply both sides by 0.131

Vs = 0.131 * P +1.683

If this was a homework question and you could not do it then it should have made you realise that you had not been paying attention in the lessons.

We are not here to give you answers. You are not allowed to post questions without showing your own attempts first. And, as Les said, if this is homework and you don't know how to do it, then ask your teacher and start paying attention in class. You are not entitled to anything here, the members of ETO VOLUNTEER their time. Don't expect to get something without giving something yourself. It is you who is arrogant. If you don't like it here, then leave. It's as simple as that.

But at least two of us DID give the answers.... Go figure... Try to help and get abuse.... Making at least two moderators unhappy ISN'T the best way to proceed...

Les Jones. You simply take 0.131 and slide it diagonally to the other side of the equation and then take 1.683 to the other side and change the sign to positive. Then read the equation backwards.
No complex multiplication required.
