Answer:
  
Step-by-step explanation:
 Let be "x" the cost in dollars of a hamburger and "y" the cost in dollars of a soft drink.
 The cost of 4 hamburguers can be represented with this expression:
 
 And the cost of 6 soft drinks  can be represented with this expression:
 
 Since the total cost for 4 hamburgers and 6 soft drinks is $34, you can write the following equation:
 
   <em>[Equation 1]</em>
  The following expression represents the the cost of 3 soft drinks:
 
 According to the information given in the exercise, the total cost for 4 hamburgers and 3 soft drinks is $25. Then, the equation that represents this is:
 
 <em> [Equation 2]</em>
 Therefore, the <em>Equation 1 </em>and the <em>Equation 2 </em>can be used to determine the price of a hamburger and the price of a soft drink
