My answer is 12 because I subtract 36 from 24 and got 12
You can get a circle by cutting horizontally and a hyperbola by cutting vertically. You can also get an ellipse and a parabola by cutting at an angle depending on whether the cut comes out the other side or not.
Make all a and constant number in different side
10-7=16z-7z+2z
3=11z
z=3/11
