Step-by-step explanation:
Number of nickels plus number of dimes equals total number of coins
so
n + d = 40
then they tell us that "there are seven times as many dimes as there are nickels"
this translates to
d = 7n
we then plug that into our first equation
and get
n + 7n = 40

add like terms
8n = 40
then divide both sides by 8
n = 40/8 = 5
