You can put this solution on YOUR website!
Let $\"+x+\"$ = ml of solution
\n" ); document.write( " $\"+80+-+x+\"$ = ml of water
\n" ); document.write( "--------------------------
\n" ); document.write( " $\"+x+%2F+%28+80+-+x+%29+=+1%2F3+\"$
\n" ); document.write( " $\"+3x+=+80+-+x+\"$
\n" ); document.write( " $\"+4x+=+80+\"$
\n" ); document.write( " $\"+x+=+20+\"$
\n" ); document.write( "20 ml of solution was used
\n" ); document.write( "-----------------------
\n" ); document.write( "check:
\n" ); document.write( " $\"+x+%2F+%28+80+-+x+%29+=+1%2F3+\"$
\n" ); document.write( " $\"+20+%2F+%28+80+-+20+%29+=+1%2F3+\"$
\n" ); document.write( " $\"+20%2F60+=+1%2F3+\"$
\n" ); document.write( " $\"+1%2F3+=+1%2F3+\"$
