Answer:

1/28

Explanation:

The expression is 7x-4y

  • x = 1/4
  • y= 3/7

Replace x by 1/4 and y by 3/7

  • 7x-4y
  • 7*(
    (1)/(4)) - 4*(
    (3)/(7)) multiply 1 by 7 and 4 by 3

  • (7)/(4) -
    (12)/(7) multiply 7/4 by 7 and 12/7 ny 4 to get the same denominator

  • (49-48)/(28)
  • 1/28
