One cat has four paws, so there are 120/4=30 cats. If a "set" of cats is two uncool cats and three cool cats, there are five cats in a set, so there are 30/5=6 sets. Since each of the six sets contains three cool cats, there are 18 cool cats in the family.
Answer:
True
Step-by-step explanation:
First, we need to recognize that

Now, we can try to solve

Multiply each side by 

As we end up with an answer that cannot be true, we know that there is no solution.
Another method to solve this would be graphing the function 
When graphed, it can be seen that there is an asymptote at x=0 meaning that there is no value for x=0.
Isolate the variable by dividing each side by factors that don’t contain the variable.
X = -2
Hope this helps!
Have a great day!
