Comparing with the standard form equation 
, since 
, then the radius of the circle is 
. Also, the center of the circle would be 
.
X=4. If k is the midpoint then JK is equal to KL. Since JK is 7 then KL is also 7 meaning JK is 14. JK is represented by the expression 4x-2 so you just set that expression equal to 14 and solve for x. Hope this helped!
