\n" ); document.write( "1. y=3x-2
\n" ); document.write( "y=x+4

\n" ); document.write( "The given is two different expressions both equal to y.
\n" ); document.write( "Use what you are apparently calling Substitution-Equal Values Method:

\n" ); document.write( "3x-2 = x+4
\n" ); document.write( "...

\n" ); document.write( "2. 5x-4y=27
\n" ); document.write( "3x+4y=29

\n" ); document.write( "The given has one equation with \"-4y\" and the other with \"+4y\".
\n" ); document.write( "Clearly, use Elimination Method:

\n" ); document.write( "8x = 56
\n" ); document.write( "...

\n" ); document.write( "3. 2x+5y=25
\n" ); document.write( "y=x+4

\n" ); document.write( "The given has one in standard form Ax+By=C; the other is in \"y=\" form.
\n" ); document.write( "Clearly, use Substitution Method

\n" ); document.write( "2x+5(x+4)=25
\n" ); document.write( "...

\n" ); document.write( "
\n" ); document.write( "
\n" );
