Answer:

x = 1 and y = 3.

Step-by-step explanation:

Given,

     ( 1 / 3 ) x + y = 10 / 3

⇒ ( 1 / 3 )x + y = 10 / 3

⇒ ( x + 3y ) / 3 = 10 / 3

⇒ x  + 3y = 10

⇒ x = 10 - 3y        ...( 1 )

 Also,

    2x + ( 1 / 4 ) y = 11 / 4

⇒ 2x + ( 1 / 4 )y = 11 / 4

⇒ ( 8x + y ) / 4 = 11 / 4

⇒ 8x + y = 11

⇒ 8( 10 - 3y ) + y = 11       { from ( 1 ) }

⇒ 80 - 24y + y = 11

⇒ -23y = 11 - 80

⇒ - 23y = - 69

⇒ y = 3

   Thus,

     x = 10 - 3y

        = 10 - 3( 3 )

        = 10 - 9

        = 1

x = 1 and y = 3.
