document.write( "I was taught to drop the absolute value sign, set up two equations-- DISABLED_event_one=  to -15 and  DISABLED_event_one=  to 15 and then solve for a.  So for this problem, I wasn't sure if I should drop the absolute value sign and then it would be -5 x 6a + 2 = -15 and -5 x 6a + 2 = 15 OR if I should first distribute the -5 as if the absolute value signs were parentheses.  Thanks so much for your help. \n" );

Further, absolute value bars are NOT parentheses, so you can't just willy-nilly distribute across them. The only thing left is do divide both sides by the coefficient outside. THEN you can drop the bars and make two equations.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "or\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "By the way: Capital Is don't make good absolute value bars.
