Question 414366: when two resistors are wired in parallel the total resistance (Rt) is determined using the following formula
1/Rt = 1/R1 + 1/R2
Solve the formula for R1
a complex fraction? I hope I typed it correctly.

1%2FRt+=+1%2FR1+%2B+1%2FR2+......solve for R1

1%2FRt-1%2FR2+=+1%2FR1++

R1%281%2FRt-1%2FR2%29+=+1++

R1+=+1%2F%281%2FRt-1%2FR2%29++

R1+=+1%2F%28%28R2-Rt%29%2FRtR2%29++

R1+=+RtR2%2F%28R2-Rt%29++
