48. If 2xy = 4x + 3y, express the value of y in terms of x.

If x-y =4 and xy=45 , then the value of (x^3 - y^3) is :

(a) If x : y = 3 : 4 , then find the value of the ratio (2x + y) : ( 9x - 2y) . (b) If x : y = 5 : 4 , then find the value of the ratio (x^(2) + xy) : (x^(2) - xy) .

In the formula (3y)/(2x -y) - 2 = 5x , what is the correct expression of y in terms of x ?

Express y of the equation (xy)/(x-y)=8 in term of x.

If x,y in R satisfy the equation x^2 + y^2 - 4x-2y + 5 = 0, then the value of the expression [(sqrtx-sqrty)^2+4sqrt(xy)]/((x+sqrt(xy)) is

The minimum value of the expression 3x + 2y (AA x, y >0) , where xy^(2) = 10 , occurs when the value of y is equal to

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

If f(2x + 3y, 2x-3y)=4xy , then find the value of f(x,y)

Express in terms of (x)/(4)-3y=7
