x^2-y^2=3
\n" ); document.write( "2x+y=3 --> y = -2x + 3
\n" ); document.write( "----------
\n" ); document.write( "Sub for y into the 1st eqn:
\n" ); document.write( " $\"x%5E2+-+%28-2x%2B3%29%5E2+=+3\"$
\n" ); document.write( " $\"-3x%5E2+%2B+12x+-+9+=+3\"$
\n" ); document.write( " $\"3x%5E2+-+12x+%2B+12+=+0\"$
\n" ); document.write( " $\"x%5E2+-+4x+%2B+4+=+0\"$
\n" ); document.write( " $\"%28x-2%29%5E2+=+0\"$
\n" ); document.write( "---------------------
\n" ); document.write( "x = 2, y = -1\r
