<h3>What is an equation?</h3>
A mathematical equation is the representation of a problem by the use of variables. Often times, an equation is formed from the factors that are in a problem.
We have to represented each of the books read with an algebraic term;
Let the number of mystery books be y
Let the number of sports books be x
Total number of books = 23
We know that;
