If `3/(x+y)` + `2/(x-y)` =2 and `9/(x+y)` `- 4/(x-y)` =1 ,then

If (1)/(x+y) + (1)/(x-y) = 4 and (2)/(x+y) + (3)/(x-y) = 9 what is the value of x ?

Solve the following system of equations: 3/(x+y)+2/(x-y)=2,\ \ \ \ 9/(x+y)-4/(x-y)=1

If 2^(x) = 4 xx 2^(y) and 9 xx 3^(x) = 3^(-y) , find the values of x and y.

If equation of hyperbola is 4(2y -x -3)^(2) -9(2x + y - 1)^(2) = 80 , then

If the circle x^2+y^2=a^2 intersects the hyperbola x y=c^2 at four points P(x_1, y_1),Q(x_2, y_2),R(x_3, y_3), and S(x_4, y_4), then x_1+x_2+x_3+x_4=0 y_1+y_2+y_3+y_4=0 x_1x_2x_3x_4=C^4 y_1y_2y_3y_4=C^4

The equation of the incircle of the triangle formed by the coordinate axes and the line 4x + 3y - 6 = 0 is (A) x^(2) + y^(2) - 6x - 6y - 9 = 0 (B) 4 (x^(2) + y^(2) - x - y) + 1 = 0 (C) 4 (x^(2) + y^(2) + x + y) + 1 = 0 (D) 4 (x^(2) + y^(2) - x - y ) - 1 = 0

If log_(9)x +log_(4)y = (7)/(2) and log_(9) x - log_(8)y =- (3)/(2) , then x +y equals
