For this case we give as data the following equation:
[tex]4x + 12 = 48[/tex]
Where "x" represents the cost of a ticket.
By clearing the value of "x" of the equation we can know the cost of a ticket.
If we subtract 12 from both sides of the equation, we have:
[tex]4x = 48-12\\4x = 36[/tex]
If we divide between 4 on both sides of the equation:
[tex]x = \frac {36} {4}\\x = 9[/tex]
Therefore, the cost of a ticket is $ 9.00
