Answer:
Step-by-step explanation:
Let [tex]L[/tex] be the number of tickets given away to listeners, and [tex]E[/tex] be the number of tickets given away to employees.
From the problem statement, we know the following two equations can be formed:
[tex]L + E = 235[/tex]
[tex]L = 4E[/tex]
If we substitue the second equation into the first, we can solve for [tex]E[/tex]:
[tex]L + E = 235[/tex]
[tex](4E) + E = 235[/tex]
[tex]5E = 235[/tex]
[tex]E = 47[/tex]
