Understanding Equations and Problem Solving

The video tutorial guides viewers through translating a word problem into an equation and solving it. Jose and Corey have a total of 114 books, with Jose having 26 more books than Corey. By letting x represent Corey's books, the equation x + (x + 26) = 114 is formed. Simplifying and solving the equation reveals Corey has 44 books, and Jose has 70 books. The solution is verified by checking the total number of books.
