Answer provided by our tutors
let
x = the number of large stones
y = the number of small stones
You want to surround the perimeter of a garden with 35 stones:
x + y = 35
for every large stone, you want to use 4 small stones:
y = 4x
by solving the system of equations:
x + y = 35
y = 4x
we find:
x = 7 large stones
y = 28 small stones
