Typo,

Let the Mexican Quest begin. (Note: I'm Hispanic, the joke stands). So let the price of your tacos a variable, say $x$, and the price of burritos be the other variable, say $y$.

So, we need two equations to solve for two variables. One of them will be the cost of the first person and the other one will be the cost of the second person, so:

$3Burritos+4Tacos=$11.33$ or $3y+4x=11.33$

$9Burritos+5Tacos=$23.56$ or $9y+5x=23.56$

Solve the system of for x and that will be the price of one taco.

3x + 4y = 11.33
9x + 5y = 23.56

3x + 4y = 11.33         times 3     =       9x + 12y = 33.99

  9x + 12y = 33.99
-
  9x + 5y = 23.56
-----------------------
             7y =  10.43
               y = 1.49


 now sub y into the one of the equations to find x... actually you don't even need to, you only need to find y, the cost of taco
