True
Because 9 is a odd number as of 1,3,5 are
8-3x=5*2
8-3x=10
-3x=10-8

There are many answers. I’ll give you three examples...
4/10
6/15
8/20
There is a pattern too, just a trick!
You have to complete the square of (x²+18x+?) as well as for (y²-36y+?)
You will find: (x+9)² + (y-18)² = 36
& this is the standard equation requested
