Small jar = x
\n" ); document.write( "Large jar = y
\n" ); document.write( "2x + y = 7.......1
\n" ); document.write( "3x + 3y = 15.....2
\n" ); document.write( "Multiply (10 by 3
\n" ); document.write( "6x + 3y = 21.....3
\n" ); document.write( "3x + 3y = 15.....2
\n" ); document.write( "Subtract (2) from (3)
\n" ); document.write( "3x = 6
\n" ); document.write( " x = 2
\n" ); document.write( "Substitute x = 2 in (1)
\n" ); document.write( "2x + y = 7
\n" ); document.write( "2(2) + y = 7
\n" ); document.write( "4 + y = 7
\n" ); document.write( " y = 7 - 4
\n" ); document.write( " y = 3
\n" ); document.write( "Small jar contains 2 litres
\n" ); document.write( "Large jar contains 3 litres.
\n" ); document.write( "Hope this helps.
