" (ii) "(2)/(x)+(3)/(y)=3" तथा "(3)/(x)+(6)/(y)=5

Find each of the following products: (i) (x - 4)(x - 4) (ii) (2x - 3y)(2x - 3y) (iii) ((3)/(4) x - (5)/(6) y) ((3)/(4)x - (5)/(6) y) (iv) (x - (3)/(x)) (x - (3)/(x)) (v) ((1)/(3) x^(2) - 9) ((1)/(3) x^(2) - 9) (vi) ((1)/(2) y^(2) - (1)/(3) y) ((1)/(2) y^(2) - (1)/(3) y)

(2) (3x)/(2)-(5y)/(3)=-2 ; (x)/(3)+(y)/(2)=(13)/(6)

Solve for x and y : ( 3x )/( 2) - ( 5y )/( 3) = - 2, ( x)/(3) + ( y)/(2) = (13)/(6)

solve (3x)/(2)-(5y)/(3) = -2 (x)/(3)+(y)/(2) = 13/6

(x)/(2) - ( y )/(9) = 6, ( x) /( 7) + ( y ) /(3) = 5 .

If log_(5)(3^(x)-4^(y))=3 and 3^((x)/(2))-2^(y)=5, then (x)/(y) is equal to

{:((1)/(2(x + 2y)) + (5)/(3(3x - 2y))=(-3)/(2)),((5)/(4(x + 2y)) - (3)/(5(3x - 2y)) = (61)/(60)):}

x+(6)/(y)=6,3x-(8)/(y)=5 then y=………
