Question

Jenny reads a book with 92 pages. Jenny's book has 13 more pages than the book Macy reads. Which equation could you solve to find how many pages, m, Macy's book has?



a m+13=92m plus 13 is equal to 92


b m=92+13m is equal to 92 plus 13


c 92m=1392 m is equal to 13


d 13m=92

Answer 1

The correct answer is a.

All you do is change M+13=92 by subtracting 13 on both sides so that 13 cancels out on the left and 13 pages are subtracted from 92, and then you get your answer, which is m=79.

You can check your work by adding 13 and 79, and then you will know that that answer is correct
