Find the center, radius, and x- and y-intercepts of the circle given by the equation 3x2 + 3y2 - 6x + 5y = 0. Now I have this problem:
solve the system by addition.
2x-4y=7
4x+2y=9
Ok so I subtract 2x-4x and get -2x
then I do -4y+2y=-2y
Now my problem looks like this;
-2x+-2y=7+9=
-2x+-2y=16
Now what?
