Lets assume there are $$x$$ games in their collection.

So, now we have

Blake found = $${3x \over 4}$$ video games

Andy found = $${3x \over 4}-18$$ video games

Back to the question... total no. of video games are $$x$$

∴ $${3x \over 4}+{3x \over 4} -18=x$$

$${6x \over 4}-x=18$$

$$2x=72$$

$$x=36$$

Hence, there are 36 video games in their collection.
