Step-by-step explanation:
Radius times 2 is the diameter!
Two consecutive odd integers whose product is 143 are 11 and 13.
I would do linear combinations
if we simplify all of them by dividing the 2nd equation by -2 and the 3rd by 3, we get
x+y+2z=5
x+y+2z=5
x+y+2z=5
which is all the same plane, so there are infnitely many solutions
