From the second equation,
\n" ); document.write( " $\"y=5-4x\"$
\n" ); document.write( "Substituting into the first,
\n" ); document.write( " $\"5-4x=x%5E2-2x-19\"$
\n" ); document.write( " $\"x%5E2%2B2x-24=0\"$
\n" ); document.write( " $\"%28x%2B6%29%28x-4%29=0\"$
\n" ); document.write( "So the second solution is,
\n" ); document.write( " $\"x-4=0\"$
\n" ); document.write( " $\"x=4\"$
\n" ); document.write( "Then,
\n" ); document.write( " $\"y%2B4%284%29=5\"$
\n" ); document.write( " $\"y=-11\"$
\n" ); document.write( ".
