(1) $\"++y+=+2x+-+2+\"$
\n" ); document.write( "(2) $\"+y+=+x+%2B+2+\"$
\n" ); document.write( "Substitute $\"y\"$ in (2) for $\"y\"$ in (1)
\n" ); document.write( " $\"+x+%2B+2+=+2x+-+2+\"$
\n" ); document.write( "Subtract $\"x\"$ from both sides
\n" ); document.write( " $\"+2+=+2x+-+2+\"$
\n" ); document.write( "Add $\"2\"$ to both sides
\n" ); document.write( " $\"+4+=+2x+\"$
\n" ); document.write( "Divide both sides by $\"2\"$
\n" ); document.write( " $\"++x+=+2+\"$
\n" ); document.write( "Now replace $\"x\"$ in (1) with $\"x+=+2\"$
\n" ); document.write( " $\"+y+=+2%2A2+-+2+\"$
\n" ); document.write( " $\"+y+=+4+-+2+\"$
\n" ); document.write( " $\"+y+=+2+\"$ \n" ); document.write( "
