Let x= the size of thge smaller tank\r
\n" ); document.write( "\n" ); document.write( "Then,
\n" ); document.write( " 2x= the size of the bigger tank(one tank needs to be twice the size of the other)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Their sum is x+2x\r
\n" ); document.write( "\n" ); document.write( "x+2x=400------------------Two tanks must have a total capacity of 400 gallons
\n" ); document.write( "3x=400
\n" ); document.write( "x=400/3 or 133.33
\n" ); document.write( "2x= 266.66\r
\n" ); document.write( "\n" ); document.write( "Therefore, the tanks must hve sizes, 133.33 and 266.66 gallons!\r
