Algebra.Com's Answer #98382 by edjones(8007)![]() ![]() You can put this solution on YOUR website! [1/(x + 1)] > [1/(x – 1)] LCD is (x+1)(x-1) \n" ); document.write( "x-1>x+1 Multiply each side by LCD to eliminate fractions. \n" ); document.write( "The equation is false because there is no number that when 1 is subtracted from it is larger than the same number when 1 is added to it. \n" ); document.write( "X[] \n" ); document.write( "The answer is the empty set. \n" ); document.write( ". \n" ); document.write( "Ed \n" ); document.write( " \n" ); document.write( " |
