Math is NOT my field, but in general:
The reciprocal of a fraction is obtained by interchanging the numerator and the denominator, i.e. by inverting the fraction.
The reciprocal of 1/6 is 6/1. Looking at the 6, 2 X 3 = 6. But when it comes to fractions, I'm lost!

Please put your subject in the "School Subject" space.
x = 3y
1/x + 1/y = 1/6
Substitute 3y for x in the second equation and solve for y. Put that value in the first equation to find x. Check by putting both values into the second equation.
