Question

1/a+1/v = 1/F
Isolate for F showing steps. Please help!

Answer 1

F(a + v) = av
F = av / (a +v)

Answer 2

\[\frac{ 1 }{ a }+\frac{ 1 }{ v }=\frac{ 1 }{ F }\]
\[F(\frac{1}{a}+\frac{1}{v})=1\]
\[F(\frac{a+v}{av})=1\]
\[\large F=\dfrac{ \dfrac{ 1 }{ a+v } }{ av }\]
\[\large F=\dfrac{ av }{ a+v }\]

Answer 3

Thanks so much guys :)
