The system of equations representing the problem is
and we have brown M&M's and
green M&M's in the cookie jar.
If we let represent the number of brown M&M's and
the number of green M&M's, then, from the sentence
"...<em>A cookie jar contains 315 M&M's. There are only brown and green M&M's in the jar</em>..."
we can construct the algebraic equation
Also, from the sentence
"...<em>The number of green M&M's is 8 times that of the brown M&M's</em>..."
we can construct the algebraic equation
overall, we have the system of equations with unknowns and
Adding the two equations, we get
Substituting this value for into the relationship
Therefore, we have brown M&M's and
green M&M's
