This if then statement is true because an 8 sided polygon is called an octagon.
So, when you simplify this equation, you get 2x+2, and assuming that the answer is 0, aka 2x+2= 0, then there is only one solution when you solve it.
Answer: One solution (-1)
(What I did:
3x-2x+x+2=
x+x+2=
2x+2 )
Answer:
