S = the age of my sister
N = the age of my nephew (my sister's son)
The ages of my sister and her son (my nephew) add up to 27 years.
A quarter of my sister’s age is double her son’s (my nephew's) age.


Solve the system below by substitution.  Before substituting,
you might first multiply the second equation through by 4 to 
clear the fraction.



You finish.
