$\"A%2BB=7\"$
\n" ); document.write( " $\"AB=-60\"$
\n" ); document.write( "Substituting,
\n" ); document.write( " $\"A=7-B\"$
\n" ); document.write( "So,
\n" ); document.write( " $\"%287-B%29B=-60\"$
\n" ); document.write( " $\"-B%5E2%2B7B=-60\"$
\n" ); document.write( " $\"B%5E2-7B-60=0\"$
\n" ); document.write( " $\"%28B-12%29%28B%2B5%29=0\"$
\n" ); document.write( "Two solutions:
\n" ); document.write( " $\"B=12\"$
\n" ); document.write( "So then,
\n" ); document.write( " $\"A%2B12=7\"$
\n" ); document.write( " $\"A=-7\"$
\n" ); document.write( "and
\n" ); document.write( " $\"B=-5\"$
\n" ); document.write( " $\"A-5=7\"$
\n" ); document.write( " $\"A=12\"$
\n" ); document.write( "The two numbers are 12 and -5.
\n" ); document.write( " \n" ); document.write( "
