Question 255432
Let's call the number of pages in Jay's book J and Mitchel's book M.  Then the first sentence tells us that:

{{{J = 3M - 182}}}

If both books have the same number of pages, then J = M.  So let's replace the J with M in our equation:

{{{M = 3M - 182}}}

Subtract 3M from both sides:

{{{-2M = -182}}}

Divide by -2:

{{{M = 91}}}

So Mitchel's book and Jay's book have 91 pages.
