6. ( 4x + 2y ) / ( 4x + 2y ) = ? as ( x /2y ) = 2 a) 8 /7 b) 9 / 7 c) 11 / 7 d) 6 /7

• the question should be what is (4x+2y)/(4x-2y) when x/2y = 2?
  solution
  x/2y = 2 means x = 4y
  substitute in first part
  (16y+2y)/(16y-2y) = 18y/14y = 9/7 answer is b)

• x/2y=2 >>> x=4y (4(4y) + 2y)/(4(4y) - 2y) = 18y/14y = 9/7 is the answer

• as x=4y
  den put x =4y
  (16y+2y)/(16y-2y)=18y/14y=9/7
  so b
