c=number o cats
d=number o dogs
has 9 fewer dogs than cats means c-9=d
has total o 15 dogs, so find cats
if d=15
c-9=15
add 9 to both sides
c=24
24 cats
The answer is 24 cats. They way you get the answer is since there is 9 fewer dogs than cats in the shelter and there are 15 dogs you would add the 9 to the 15 to get the total amount of cats. Hope this helps
