You can put this solution on YOUR website!
p = number of pennies
n = number of nickels
d = number of dimes

n = 3p
d = p - 2
p + 5n + 10d = 110

Write everything in terms of p.

p + 5n + 10d = 110
p + 5(3p) + 10(p-2) = 110
p + 15p + 10p - 20 = 110
26p = 130
p = 5

Megan has 5 pennies, 15 nickels, and 3 dimes.
