Answer:
 Cost of a single Mucho beef burrito: 
 Cost of a double Mucho beef burrito: 
Step-by-step explanation:
<h3>
 The exercise is: "The Little Mexican restaurant sells only two kinds of beef burritos: Mucho beef and Mucho Mucho beef. Last week in the restaurant sold 16 orders of the single Mucho variety and 22 orders of the double Mucho. If the restaurant sold $231 Worth of beef burritos last week and the single neutral kind cost $1 Less than the double Mucho, how much did each type of burrito cost?"</h3>
 Let be "x" the the cost in dollars of a single Mucho beef burrito and "y" the cost in dollars of a double Mucho burrito.
 Set a system of equations:
 
 To solve this system you can apply the Substitution Method:
 1. Substitute the second equation into the first equation and solve for "y":
 
 2. Substitute the value of "y" into the second equation and evaluate in order to find the value of "x":
 
 
        
             
        
        
        
F(x)= -4x+9
Multiply f*x
xF=9+4x
Solve for X: -4x+xF=9+4x-4x=0
Combine like terms: -4x+4x=0
-4x+xF=9+0= 9
-9+-4x +xF = 0.
