Q:6x+5y=7x+3y+1=2(x+6y-1)

If (3x -4y) : (2x -3y) = (5x -6y) : (4x -5y) , find : x : y .

6/(x+y)=7/(x-y)+3 , 1/(2(x+y))=1/(3(x-y))

Add the algebraic expressions: 4x y^2-7x^2y ,\ 12 x^2y-6x y^2,\ -3x^2y+5x y^2

Find the value fo x:y, if (7x - 15y)/(4x + 6y) = (5)/(6).

Factorize each of the following algebraic expressions: 6x(2x-y)7y(2x-y)2r(y-x)+s(x-y)7a(2x-3)+3b(2x-3)9a(6a-5b)-12a^(2)(6a-5b)

If 10y=7x-4 and 12x+18y=1 . Find the value of 4x+6y and 8y-x .

Solve for x and y : (1)/( 7x ) + ( 1) /( 6y) = 3, (1)/( 2x) - (1)/( 3y ) = 5 (x ne 0, y ne 0)

If P=7x^2+5x y-9y^2,\ Q=4y^2-3x^2-6x y and R=-4x^2+x y+5y^2, show that P+Q+R=0.

If P=7x^2+5x y-9y^2,\ Q=4y^2-3x^2-6x y and R=-4x^2+x y+5y^2, show that P+Q+R=0.
