1. $\"y+=+x%5E2+%2B+5\"$
\n" ); document.write( "2. $\"6x+%96+y+=+3\"$
\n" ); document.write( "Substitute,
\n" ); document.write( " $\"6x-%28x%5E2%2B5%29=3\"$
\n" ); document.write( " $\"-x%5E2%2B6x-5=3\"$
\n" ); document.write( " $\"-x%5E2%2B6x-8=0\"$
\n" ); document.write( " $\"x%5E2-6x%2B8=0\"$
\n" ); document.write( " $\"%28x-4%29%28x-2%29=0\"$
\n" ); document.write( "Two solutions:
\n" ); document.write( " $\"x-4=0\"$
\n" ); document.write( " $\"x=4\"$
\n" ); document.write( "Then,
\n" ); document.write( " $\"y=4%5E2%2B5\"$
\n" ); document.write( " $\"y=16%2B5\"$
\n" ); document.write( " $\"y=21\"$
\n" ); document.write( "and
\n" ); document.write( " $\"x-2=0\"$
\n" ); document.write( " $\"x=2\"$
\n" ); document.write( "Then,
\n" ); document.write( " $\"y=2%5E2%2B5\"$
\n" ); document.write( " $\"y=4%2B5\"$
\n" ); document.write( " $\"y=9\"$
\n" ); document.write( "(4,21) and (2,9) \n" ); document.write( "
