System of equations, variables, cost, tickets, adults, children.

For this case we must solve a system of equations with two variables represented by the tickets of students and adults of a school production.

We define the variables according to the given table:

We then have the following system of equations:

From the first equation, we clear the value of the variable c:

The value that could replace c in the table is:
