You can put this solution on YOUR website!
Let $\"+w+\"$ = ounces of water to be added
\n" ); document.write( " $\"+.55%2A38+=+20.9+\"$ ounces of boric acid
\n" ); document.write( "in 55% solution
\n" ); document.write( "----------------
\n" ); document.write( " $\"+20.9+%2F+%28+38+%2B+w+%29+=+.38+\"$
\n" ); document.write( " $\"+20.9+=+.38%2A%28+38+%2B+w+%29+\"$
\n" ); document.write( " $\"+20.9+=+14.44+%2B+.38w+\"$
\n" ); document.write( " $\"+.38w+=+6.46+\"$
\n" ); document.write( " $\"+w+=+17+\"$
\n" ); document.write( "17 ounces of water should be added
\n" ); document.write( "check:
\n" ); document.write( " $\"+20.9+%2F+%28+38+%2B+17+%29+=+.38+\"$
\n" ); document.write( " $\"+20.9+%2F+55+=+.38+\"$
\n" ); document.write( " $\"+20.9+=+.38%2A55+\"$
\n" ); document.write( " $\"+20.9+=+20.9+\"$
\n" ); document.write( "OK \n" ); document.write( "
