Two step equations word problems! HELP!!

Question

I'm stuck on this word problem and how to set it up:

Westyn is 5 years older than two fifths the age of Dayana. If Westyn is 25 years old, how old is Dayana?

Answer 1

W = 5 + 2D/5

25= 5 + 2D/5

2D/5 = 25-5 = 20

D = (5/2)20 = 50 years old for Dayana

W = 5+ 2(50)/5 = 5+ 20 = 25 years old for Westyn
