If `x:y= 5:2,` then `(8x + 9y): (8x+ 2y)` is:

If x:y=4:5 , then (2x+3y): (8x-5y) is equal to :

If 8x^2 + y^2 -12x -4xy+9 =0 , then the value of (14x-5y) is:

If 8x^2+y^2- 12x - 4xy + 9= 0 , then the value of (14x - 5y) is: यदि 8x^2+y^2- 12x - 4xy + 9= 0 है, तो (14x - 5y) का मान ज्ञात करें |

If 4x + 6y = 3 xy and 8x + 9y = 5xy then

If 5x + 6y : 8x + 5y = 8 : 9 , find : x : y .

If 4x^(2) + 12xy -8x+9y^(2) -12y = (ax+by) (ax+by-4) , then the value of a^(2) +b^(2) is

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)
