Let $\"+x+\"$ = litres of water to be added
\n" ); document.write( " $\"+.25%2A6000+=+1500+\"$ = litres of salt in 25% mixture
\n" ); document.write( "---------------------
\n" ); document.write( " $\"+1500+%2F+%28+x+%2B+6000+%29+=+.23+\"$
\n" ); document.write( " $\"+1500+=+.23%2A%28+x+%2B+6000+%29+\"$
\n" ); document.write( " $\"+1500+=+.23x+%2B+1380+\"$
\n" ); document.write( " $\"+.23x+=+120+\"$
\n" ); document.write( " $\"+x+=+521.74+\"$
\n" ); document.write( "521.74 litres of water are needed
\n" ); document.write( "check:
