Question 12160
Let x = number of people
y = number of puppies


Since all the people and puppies alike have one body, this means that 
x+y = 40


Assuming that all the people have 2 legs and the puppies all have 4 legs each, 
2x + 4y = 116.


Solve the system of equations, either by elimination method or substitution.
