Algebra.Com's Answer #19861 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! The LCD is 5(x+1) \n" ); document.write( "Convert each fraction to having that denominator, as follows: \n" ); document.write( "1/[5(x+1)] -3(5)/[5(x+1)] - 7(x+1)/[5(x+1)] \n" ); document.write( "Now they all have the same denominator. Combine the numerators. \n" ); document.write( "[1-15-7x-7]/[5(x+1)] \n" ); document.write( "[-21-7x]/LCD \n" ); document.write( "-7[3+x)/LCD \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
