\n" ); document.write( "\n" ); document.write( "3x+4y=12\r

\n" ); document.write( "----------------------
\n" ); document.write( "\"getting y by itself\" means getting it on one side of the equal sign.
\n" ); document.write( "Do what it take to do that.
\n" ); document.write( "----
\n" ); document.write( "2x-3y=9
\n" ); document.write( "Add 3y to both sides.
\n" ); document.write( "Divide by 3.
\n" ); document.write( "======================
\n" ); document.write( "x+2y-4=0
\n" ); document.write( "Add 4
\n" ); document.write( "subtract x
\n" ); document.write( "divide by 2
\n" ); document.write( "====================
\n" ); document.write( "3x+4y=12
\n" ); document.write( "similar to the 2 above.\r
\n" ); document.write( "\n" ); document.write( "
