\n" ); document.write( " and \"the first number minus the second number is-6\"
\n" ); document.write( ":
\n" ); document.write( "2a + b = 42
\n" ); document.write( " a - b = -6
\n" ); document.write( "--------------adding eliminates b, find a
\n" ); document.write( "3a = 36
\n" ); document.write( "a = 36/3
\n" ); document.write( "a = 12
\n" ); document.write( ":
