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.
