Question

Miriam read a book with an unknown number of pages. The first week, she read five less than 1/3 of the pages. The second week, she read 171 more pages and finished the book. Write an equation that represents the total number of pages in the book.

Answer 1

Answer: 249 = x

Step-by-step explanation:

((1/3)x - 5) + 171 = x

combine like terms...move the x’s to one side...

166 = (2/3)x

get x by itself...

166 (3/2) = x

249 = x

Answer 2

((1/3)x - 5) + 171 = x
combine like terms...move the x’s to one side...
166 = (2/3)x
get x by itself...
166 (3/2) = x
249 = x
