As long as you do the same thing to both sides
\n" ); document.write( "of the equation, it's OK
\n" ); document.write( " $\"-20+=+-4x+-+6x\"$
\n" ); document.write( "First multiply both sides by $\"-1\"$
\n" ); document.write( " $\"%28-1%29%2A%28-20%29+=+%28-1%29%2A%28-4x%29+-+%28-1%29%2A6x\"$
\n" ); document.write( "Now you simply have to know that
\n" ); document.write( "(-)x(-) = (+)
\n" ); document.write( " $\"20+=+4x+%2B+6x\"$
\n" ); document.write( " $\"x\"$ is a common factor in $\"4x\"$ and $\"6x\"$
\n" ); document.write( "so, you can express the right sides as
\n" ); document.write( " $\"x%2A%284+%2B+6%29\"$
\n" ); document.write( " $\"x%2A10\"$
\n" ); document.write( "Now the equation becomes
\n" ); document.write( " $\"20+=+10x\"$
\n" ); document.write( "Divide both sides by $\"10\"$
\n" ); document.write( " $\"x+=+2\"$
\n" ); document.write( " \n" ); document.write( "

\n" );
