Rod a is twice as long as rod b, rod c is 1/12m shorter than rod b. If rod c is 1/6m long, find the total length of Rod a and Rod b

I thought it would be 2x+(x+1/12)+1/6

B = A/2

B = C + 1/12 = 1/6 + 1/12 = 2/12 + 1/12 = ?

Put answer to second equation into the first to find A, then add the two.
So A= 1/4
B= 1/8
C= 1/6 right?
The question was to find the length of A and B together.

a+b = 2b+b = 3b = 3(c + 1/12) = 3(1/6 + 1/12) = 3(3/12) = 3(1/4) = 3/4
You rock! Thanks!!
