\"=>\" means implies
\n" ); document.write( "3(x) + 7 = 4\r
\n" ); document.write( "\n" ); document.write( "# subtract 7 from both sides of the equation
\n" ); document.write( "=> 3(x) + 7 - 7 = 4 - 7 # by equality property a = b => a+c = b+c
\n" ); document.write( "=> 3(x) + 0 = -3
\n" ); document.write( "=> 3(x) = -3
\n" ); document.write( "=> x = -3/3
\n" ); document.write( "=> x = -1 is the solution \n" ); document.write( "

\n" );
