Define a variable ** Let x = the number of books Anne has.
Write an equation ** Then x + 25 + x + 12 + x = 85
Combine like terms ** 3x + 37 = 85
Subtract 12 from both sides ** 3x = 48
Divide by 3 ** x = 48 / 3 = <<48/3=16>>16 books
How many books does Fawn have? ** Anne has 12 fewer books than Fawn, so Fawn has 16 + 12 = 28 books.
