d dogs
c cats
-----------------------------
dogs is 2 less than 3 times cays cats,..
-----------------------------

d=3c-2


-------------------------------------
if you add 4 to each the ratio of cats to dogs will be 1/2.
-------------------------------------

%28c%2B4%29%2F%28d%2B4%29=1%2F2


Try substituting for d in the ratio equation.
%28c%2B4%29%2F%283c-2%2B4%29=1%2F2
%28c%2B4%29%2F%283c%2B2%29=1%2F2
2%28c%2B4%29=3c%2B2
2c%2B8=3c%2B2
highlight%286=c%29


Find d dogs
d=3c-2
d=3%2A6-2
d=18-2
highlight%28d=16%29
