You can put this solution on YOUR website!
At the start $\"+30+\"$ ounces are gold and
\n" ); document.write( " $\"+120+\"$ ounces are silver
\n" ); document.write( "-----------------------
\n" ); document.write( "You are not changing the ounces of gold
\n" ); document.write( "only the ounces of silver
\n" ); document.write( "Let $\"+s+\"$ = ounces of silver to be added
\n" ); document.write( " $\"++30+%2F+%28+150+%2B+s+%29+=+.05+\"$
\n" ); document.write( " $\"+30+=+.05%2A%28+150+%2B+s+%29+\"$
\n" ); document.write( " $\"+30+=+7.5+%2B+.05s+\"$
\n" ); document.write( " $\"+.05s+=+22.5+\"$
\n" ); document.write( " $\"+s+=+22.5+%2F+.05+\"$
\n" ); document.write( " $\"+s+=+450+\"$
\n" ); document.write( "450 ounces of silver must be added
\n" ); document.write( "check:
\n" ); document.write( " $\"++30+%2F+%28+150+%2B+s+%29+=+.05+\"$
\n" ); document.write( " $\"++30+%2F+%28+150+%2B+450+%29+=+.05+\"$
\n" ); document.write( " $\"+30+%2F+600+=+.05+\"$
\n" ); document.write( " $\"+30+=+.05%2A600+\"$
\n" ); document.write( " $\"+30+=+30+\"$
\n" ); document.write( "OK\r
