`1/x+1/y=1/24 ,2/x+1/y=1/8`

1/(2x)-1/y=-1 , 1/x+1/(2y)=8

Find the value of ( 1/x + 1/y ) ( 1/x - 1/y ) ( 1/x^2 + 1/y^2 )

Solve the following simultaneous equations 1/(3x+y)+1/(3x-y)=3/4,1/(2(3x+y))-1/(2(3x-y))=-1/8 .

What is the Simplified value of: 1/8 { (x + 1/y)^2 - (x - 1/y)^2}

Solve the following pairs of equations: (1)/(2x)-(1)/(y)=-1, (1)/(x)+(1)/(2y)= -8, x, y ne 0

Solve the following simultaneous equations. (1)/(3x + y) + (1)/(3x - y) = (3)/(4) , (1)/(2(3x + y)) - (1)/(2(3x - y)) = - (1)/(8)

Solve for x and y : (1)/(2x) - (1)/(y) = - 1, (1)/(x) + (1)/(2y)= 8 ( x ne 0 , y ne 0 )
