We know nothing about the third number, so let's call it y. So, we have $\"75=x%2B%28x%2B8%29%2By\"$ which simplifies to $\"75=2x%2B8%2By\"$ . Further simplification results in $\"67=2x%2By\"$ . Continue solving for x and we get $\"67-y=2x\"$ and finally $\"%2867-y%29%2F2=x\"$ . \n" ); document.write( "
