Answer:
Euler's Formula states that:
V -E +F = 2 meaning that the vertices minus the edges plus the faces of a convex polyhedron will always equal two.
So, for the initial question, we have 40 edges and 24 faces.
So, vertices = 2 + Edges -Faces
Vertices = 2 + 40 - 24
Vertices = 18

I don't really understand your question, but it think it goes like this:
x-17-20=180
gather common terms
x-37=180
move 37 to other side
x=180+37
addition
x=217
