Let $\"+x+\"$ = mass of silver to be added
\n" ); document.write( " $\"+%28+48+%2B+x+%29+%2F+%28+48+%2B+72+%29+=+.46+\"$
\n" ); document.write( " $\"+48+%2B+x+=+.46%2A120+\"$
\n" ); document.write( " $\"+x+=+55.2+-+48+\"$
\n" ); document.write( " $\"+x+=+7.2+\"$
\n" ); document.write( "7.2 lbs of silver must be added
\n" ); document.write( "check:
\n" ); document.write( " $\"+%28+48+%2B+7.2+%29+%2F+%28+48+%2B+72+%29+=+.46+\"$
\n" ); document.write( " $\"+55.2+%2F+120+=+.46+\"$
\n" ); document.write( " $\"+55.2+=+.46%2A120+\"$
