Question

1/x+1/y=1/z
Solve for y please
Thanks

Answer 1

Notice 1/y = 1/z - 1/x = (x-z)/xz

So y = xz/(x-z)

Answer 2

\[\Large \frac1x+\frac1y=\frac1z\]

\[\Large yz+xz=xy \]

\[\Large xz=xy-yz\]

\[\Large xz=y(x-z)\]

\[\Large \frac{xz}{x-z}=y\]

\[\Large y=\frac{xz}{x-z}\]

Answer 3

wow, thanks to both of you.
