Answer:
m = 123, g = 273
Explanation:
m is the number of monkeys, g is the number of giraffes. We will use a system of equations.
m + g = 396
g = 2m + 27
Plug g into the first equation.
m + 2m + 27 = 396
Add like terms.
3m + 27 = 396
Simplify.
m = 123
Plug the value of m into the second equation
g = 2(123) + 27
Simplify
g = 273
