\n" ); document.write( " $\"x%2By=14\"$
\n" ); document.write( " $\"x=14-y\"$ Use this to substitute for x.
\n" ); document.write( " $\"x%5E2%2By%5E2=196\"$ Substitute for x.
\n" ); document.write( " $\"%2814-y%29%5E2%2By%5E2=196\"$
\n" ); document.write( " $\"-y%5E2-28y%2B196%2By%5E2=196\"$ Subtract 196 from each side.
\n" ); document.write( " $\"-28y=0\"$ Divide each side by -28
\n" ); document.write( " $\"y=0\"$
\n" ); document.write( " $\"x=14-y\"$ = $\"14-0=14\"$
\n" ); document.write( "ANSWER: The solution is (14,0)
