I need to find three unknown resistances given the following three equations:
[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.
