I need to find three unknown resistances given the following three equations:(adsbygoogle = window.adsbygoogle || []).push({});

[tex]

\frac{1}{R_2+R_3} + \frac{1}{R_1} = \frac{1}{670}

[/tex]

[tex]

\frac{1}{R_1+R_3} + \frac{1}{R_2} = \frac{1}{679}

[/tex]

[tex]

\frac{1}{R_1+R_2} + \frac{1}{R_3} = \frac{1}{1349}

[/tex]

I figured since there are three unknowns and three equations it is possible, but I can't see how its done.
