$\"A%2BB=-4\"$
\n" ); document.write( " $\"A%2AB=-21\"$
\n" ); document.write( "From the first equation,
\n" ); document.write( " $\"A=-4-B\"$
\n" ); document.write( "Substitute into the second,
\n" ); document.write( " $\"-%284%2BB%29B=-21\"$
\n" ); document.write( " $\"4B%2BB%5E2=21\"$
\n" ); document.write( " $\"B%5E2%2B4B-21=0\"$
\n" ); document.write( " $\"%28B%2B7%29%28B-3%29=0\"$
\n" ); document.write( "Two solutions:
\n" ); document.write( " $\"B%2B7=0\"$
\n" ); document.write( " $\"B=-7\"$
\n" ); document.write( "Then,
\n" ); document.write( " $\"A-7=-4\"$
\n" ); document.write( " $\"A=3\"$
\n" ); document.write( "and
\n" ); document.write( " $\"B-3=0\"$
\n" ); document.write( " $\"B=3\"$
\n" ); document.write( " $\"A%2B3=-4\"$
\n" ); document.write( " $\"A=-7\"$
\n" ); document.write( "The two integers are -7 and 3.
\n" ); document.write( "The largest integer is 3.\r
