The total electrical resistance R of two resistors connected in parallel with resistances R1 and R2 is given by 1/R=1/R1+1/R2. One resistor has a resistance of 2.3 ohms. Let x be the resistance of the second resistor. Express the total resistance R as a function of x. How do I go about this?

Type "1/R=1/2.3+1/x solve for x" into WolframAlpha . com and click "Show steps"

Oops, I meant "1/R=1/2.3+1/x solve for R"
