Using a system of equations, the meaning of point R is given as follows:
A number of books and their cost where both subscriptions cost the same.
<h3>What is a system of equations?</h3>
A system of equations is when two or more variables are related, and equations are built to find the values of each variable. In a graph, the solution to the system is the intersection point of the two equations.
In this problem, the point R is the point in which:
3y = 96.
That is, the point in which the prices are equal, hence:
A number of books and their cost where both subscriptions cost the same.
