Algebra.Com's Answer #96792 by nycsharkman(136)![]() ![]() ![]() You can put this solution on YOUR website! Hello! What you have here is called a fractional equation. The first thing you should do is clear the fractions by, as you said, multiplying every term on both sides of the equation by the LCD.\r \n" ); document.write( "\n" ); document.write( "Our LCD in this case is: (3x + 1)(9x + 3)(6)\r \n" ); document.write( "\n" ); document.write( "I will multiply every term on both sides by the LCD.\r \n" ); document.write( "\n" ); document.write( "5x/(3x + 1) times (3x + 1)(9x + 3)(6) = 5x(9x + 3)(6)\r \n" ); document.write( "\n" ); document.write( "1/(9x + 3) times (3x + 1)(9x + 3)(6) = -(3x + 1) (6)\r \n" ); document.write( "\n" ); document.write( "7/6 times (3x + 1)(9x + 3)(6) = 7(3x + 1) (9x + 3)\r \n" ); document.write( "\n" ); document.write( "Here is what we have now:\r \n" ); document.write( "\n" ); document.write( "5x(9x + 3)(6)-(3x + 1) (6)= 7(3x + 1) (9x + 3)....Notice that the fractions are gone.\r \n" ); document.write( "\n" ); document.write( "Can you finish the question now?\r \n" ); document.write( "\n" ); document.write( "If not, write back.\r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
