<PRE><B>Question 422961</B>
Marcos had 15 coins in nickels and quarters. 
n + q = 15
-----------------------
He had 3 more quarters than nickels. 
q = n + 3
-----------------------------------
He wrote a system of equations to represent this situation, letting n be the number of nickels and q represent the number of quarters. Then he solved the system by graphing. What is the solution?
{{{graph(400,300,-10,10,-10,10,15-x,x+3)}}}
