This is such an easy system so either can be used.
\n" ); document.write( "SUBSTITUTION
\n" ); document.write( "\"x%5E2+%2B+y+=+0\" ------ Considering X is the same as x ------ eq (i)
\n" ); document.write( "y = x - 2 ------ eq (ii)
\n" ); document.write( "\"x%5E2+%2B+x+-+2+=+0\" ------ Substituting x - 2 for y in eq (i)
\n" ); document.write( "Solve this quadratic for x, noting that it CAN be factored.
\n" ); document.write( "Then substitute each value for x into any of the 2 original equations to get 2 corresponding values for y\r
\n" ); document.write( "\n" ); document.write( "ELIMINATION
\n" ); document.write( "\"x%5E2+%2B+y+=+0\" ------ Considering X is the same as x ------ eq (i)
\n" ); document.write( "y = x - 2____- x + y = - 2 ------ eq (ii)
\n" ); document.write( "\"x%5E2+%2B+x+=+2\" ------- Subtracting eq (ii) from eq (i)
\n" ); document.write( "\"x%5E2+%2B+x+-+2+=+0\"

\n" ); document.write( "Then substitute each value for x into any of the 2 original equations to get 2 corresponding values for y
\n" ); document.write( "I guess it comes down to which method one prefers. \n" ); document.write( "
