You first want to get yy to one side, and the numbers to the other.

Explanation:

Subtract 1 1/3113 from both sides:

y+cancel(1 1/3)-cancel(1 1/3)=3 1/18-1 1/3

To work this, we have to multiply the 1/3 by 1 disguised as 6/6:

y=3+1/18-1-(1/3xx6/6)

y=3-1+1/18-6/18=2-5/18; we split the 2

y=(1+18/18)-5/18=1+13/18=1 13/18
