If there are 8 more solar systems for every planet in the galaxy, there are 8+1 = <<8+1=9>>9 solar systems for every planet.
Since the number of planets is 20, there are 20*9 = <<20*9=180>>180 solar systems in the galaxy.
Altogether, there are 180+20 = <<180+20=200>>200 solar systems and planets in the galaxy.
