{{{d=3c-2}}}



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


{{{(c+4)/(d+4)=1/2}}}



Try substituting for d in the ratio equation.
{{{(c+4)/(3c-2+4)=1/2}}}

{{{(c+4)/(3c+2)=1/2}}}

{{{2(c+4)=3c+2}}}

{{{2c+8=3c+2}}}

{{{highlight(6=c)}}}



Find d dogs
{{{d=3c-2}}}
{{{d=3*6-2}}}
{{{d=18-2}}}
{{{highlight(d=16)}}}
