To find out how many model spaceships Sylvester has, we can first set up an equation based on the given information.

Let's say Sylvester has x model spaceships.

Given that Bobby has 3 times as many model spaceships as Sylvester, we can express Bobby's number of spaceships as 3x.

And we know that Bobby has 21 spaceships, so we can write the equation:

3x = 21

To solve for x (the number of spaceships Sylvester has), we divide both sides of the equation by 3:

3x / 3 = 21 / 3

x = 7

Therefore, Sylvester has 7 model spaceships.

21/3 = 7
