If x=2 and y=3, then find the values of
`(i) (2x+3y)/(4x-3y) " "(ii) (2x^(2)-7x+2y)/(2y^(2)-7y+2x)`

If x =3 and y=1, then find the values of (i) 3x-2y" "(ii) (22)/(3)x^(2)-(7)/(2)y^(2)

If x=5 and y=-2 , then find the value of (i) (8x-2y+5)/(2x+4ty+12) " "(ii) (5x-6y-7)/(3x+6y+12)

If 2x+3y=8 and x y=2 , find the value of 4x^2+9y^2

If x:y= 3: 4, then the value of (5x - 2y)/(7x + 2y) =

If 7x - 15y = 4x + y , find the value of x: y . Hence, use componendo and dividendo to find the values of : (i) (9x + 5y)/(9x - 5y) (iI) (3x^(2) + 2y^(2))/(3x^(2) - 2y^(2))

If 3x-7y=10\ and x y=-1, find the value of 9x^2+49 y^2

If ((2x-y)/(x+2y))=(1)/(2), then find the value of ((3x-y)/(3x+y))

If 3x+5y=15 and x-2y=10 , what is the value of 2x+7y ?
