tank 1 = x
\n" ); document.write( "tank 2 = y
\n" ); document.write( "x+y=54
\n" ); document.write( "y=9+2x
\n" ); document.write( "x+9+2x=54
\n" ); document.write( "3x=54-9
\n" ); document.write( "3x=45
\n" ); document.write( "x=45/3
\n" ); document.write( "x=15
\n" ); document.write( "substituting x to find y
\n" ); document.write( "y=9+2x
\n" ); document.write( "y=9+2*15
\n" ); document.write( "y=9+30
\n" ); document.write( "y=39
\n" ); document.write( "one tank holds 15 gallons and the other tank holds 39 gallons
