Substitute the second equation into the first,

\n" ); document.write( " $\"x%5E2%2B4x%5E2%2B8x%2B4%2B2x-24=0\"$
\n" ); document.write( " $\"5x%5E2%2B10x-20=0\"$
\n" ); document.write( " $\"x%5E2%2B2x-4=0\"$
\n" ); document.write( "You can complete the square or use the quadratic equation to solve for x,
\n" ); document.write( " $\"x%5E2%2B2x%2B1-4=1\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"%28x%2B1%29%5E2=5\"$
\n" ); document.write( " $\"x%2B1=0+%2B-+sqrt%285%29\"$
\n" ); document.write( " $\"x=-1+%2B-+sqrt%285%29\"$
\n" ); document.write( "To find y, substitute into the second equation.
