1. This one was solved using substitution:\r
\n" ); document.write( "\n" ); document.write( " x + y = 2
\n" ); document.write( " 4y = -4x + 8
\n" ); document.write( "Answer: x = 2−y\r
\n" ); document.write( "\n" ); document.write( "and\r
\n" ); document.write( "\n" ); document.write( "2. This one was solved using elimination:
\n" ); document.write( " x + y = 2
\n" ); document.write( " 4y = -4x + 8
\n" ); document.write( "Answer: (x, 2 - x)\r
\n" ); document.write( "\n" ); document.write( "The question I have is \"what does this mean for the solution?\"
\n" ); document.write( "--------
\n" ); document.write( "In both cases, the equations are dependent. It's the same equation twice.
\n" ); document.write( "---> infinite # of solutions, no unique solution.\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "

\n" );
