Answer:
3x + 2y = 38,  3a + 2b = 38
Step-by-step explanation:
An equation may be defined as a statement that shows two mathematical expressions to be equal. It is to equate one thing to another thing. 
In the context, two different equations for the situations are :
i). Let the shirt be represented by x
    And the socks be represented by y
Therefore, according to the question, 
    3x + 2y = 38
ii). Let the shirt be represented by a
    And the socks be represented by b
Therefore, according to the question, 
    3a + 2b = 38
 
        
             
        
        
        
You have to multiply the original price by 1/3 and then multiplying it by 2:
y=1/3x(2)
y=1/3(28.5)(2)
y=9.50(2)
y=19
$19.5
This is 2/3 of the original price (1/3 off).
