Can't understand what you are trying to type.
An example of a circle is
x^2 + y^2 = 25
An example of a straight line equation could be
20x + 7y = 19
Repost by typing in this simple way
Consider the equation of a circle
2 2
x x y y − + − − = 2 4 4 0.
If the line
2 0 x y a − + =
is its
diameter. Then find the value of a.
