a = larger
\n" ); document.write( "b = smaller
\n" ); document.write( "a + b = 2a - 4
\n" ); document.write( "subtract 2a from both sides
\n" ); document.write( "-a + b = -4
\n" ); document.write( "a - 3b = -20
\n" ); document.write( "add these equations
\n" ); document.write( "-2b = -24
\n" ); document.write( "b= 12
\n" ); document.write( "a - 3b = -20
\n" ); document.write( "a - 3*12 = -20
\n" ); document.write( "a - 36 = -20
\n" ); document.write( "a = 16
\n" ); document.write( "check
\n" ); document.write( "16 + 12 = 2*16 - 4
\n" ); document.write( "28 = 32 - 4
\n" ); document.write( "28 = 28
\n" ); document.write( "also
\n" ); document.write( "a - 3b = -20
\n" ); document.write( "16 - 3*12 = -20
\n" ); document.write( "16 - 36 = -20
\n" ); document.write( "-20 = -20
\n" ); document.write( "OK
\n" ); document.write( "
\n" );
