Question

The sum of the x-coordinates of the intersection of
x2+ y2= 36 and x2- y2=
6 is

Priyanka Kedia · Accepted Answer

The given equation be as,x2+y2=36                 
 1x2-y2=6                   
 2Adding equation 1 and 2,we have,2x2=42⇒x2=21⇒x=±21Thus, sum of x-coordinates=21+-21=0

The sum of the x-coordinates of the intersection of x2+ y2= 36 and x2- y2= 6 is

The sum of the x-coordinates of the intersection of x²+ y²= 36 and x²- y²= 6 is
