Finding resistance of single resistor

  1. Feb 5, 2017 #1
    1. The problem statement, all variables and given/known data
    Two resistors are connected in parallel. The total resistance of the combination is 6.0 ohms. If one of the resistors is 10 ohms, what is the value of the other?

    2. Relevant equations
    1/RT= 1/R1+1/R2

    3. The attempt at a solution
    I got 15 just by doing trial and error, and I'm pretty sure it's the right answer but how would you solve this using the equation?

    Via algebra, of course. What have you tried?
