Solve the system using substitution.\r
\n" ); document.write( "\n" ); document.write( "y = 3x - 6
\n" ); document.write( "-3x + y = -6
\n" ); document.write( "-----
\n" ); document.write( "Sub for y in the 2nd eqn:
\n" ); document.write( "-3x + (3x-6) = -6
\n" ); document.write( "-6 = -6
\n" ); document.write( "--------
\n" ); document.write( "--> Dependent. The 2 eqns are the same, no unique solution.
\n" ); document.write( "
\n" ); document.write( "
\n" );
