Answer 1

The vampires won 12 games.

Explanation:

This is basically a system of equations problem. If we use the letter W to represent the number of wins, and the letter L to represent losses, the info we're given is below:

`W+L=20`
They played 20 games, so their wins and losses must add to 20.

`W=L+4`
They won 4 more than they lost.

Since we know that `W=L+4`, we can substitute `L+4` in for `W` in the first equation.

`L+4+L=20`
`2L+4=20`
`2L=16`
`L=8`

They lost 8 games, which means they won 12 (just adding 4).
