Let $\"+c+\"$ = the capacity of the tank
\n" ); document.write( "given:
\n" ); document.write( " $\"+%284%2F5%29%2Ac+-+190+=+%281%2F6%29%2Ac+\"$
\n" ); document.write( "Multiply both sides by $\"+30+\"$
\n" ); document.write( " $\"+24c+-+5700+=+5c+\"$
\n" ); document.write( " $\"+19c+=+5700+\"$
\n" ); document.write( " $\"+c+=+300+\"$
\n" ); document.write( "The capacity is 300 liters
\n" ); document.write( "----------------------
\n" ); document.write( "check:
\n" ); document.write( " $\"+%284%2F5%29%2A300+=+240+\"$
\n" ); document.write( " $\"+240+-+190+=+50+\"$
\n" ); document.write( " $\"+6%2A50+=+300+\"$ liters
\n" ); document.write( "OK \n" ); document.write( "
