\n" ); document.write( " $\"%281%2F2%29x\"$ = $\"4\"$ .\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Multiply both sides by 2 to get x = 8.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Or divide both sides by the factor $\"1%2F2\"$ to get the same.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Cancel the factor $\"1%2F2\"$ in both sides, in other words.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "It is how the cancellation idea works.\r
