NEED HELP

A coin collection has 33 quarters and nickels. The number of nickels is 5 greater than
three times the number of quarters. How many coins of each type are there? Write a
system of equations and solve using substitution.

Answer 1

7 quarters

26 nickels

Explanation:

x = number of quarters

y = number of nickels

x + y = 33

y = 3x + 5

x + 3x + 5 = 33

4x = 28

x = 7

y = 3×7 + 5 = 26
