\r\n" );
document.write( "Given  = A, we want to find \r\n" );
document.write( "\r\n" );
document.write( "     = A\r\n" );
document.write( "\r\n" );
document.write( "Multiply both sides by 3:\r\n" );

document.write( "A + B + C = 3A\r\n" );
document.write( " \r\n" );
document.write( "    B + C = 2A\r\n" );
document.write( "\r\n" );
document.write( "Divide both sides by 2:\r\n" );
document.write( "\r\n" );
