Algebra.Com's Answer #64470 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! Solve and check the following eqaution for x: \n" ); document.write( "x/(x-5) +2 = 5/(x-5) \n" ); document.write( "Multiply both sides by (x-5) to get: \n" ); document.write( "x + 2(x-5) = 5 \n" ); document.write( "x + 2x -10 = 5 \n" ); document.write( "3x= 15 \n" ); document.write( "x=5 \n" ); document.write( "------- \n" ); document.write( "But x cannot be 5 because that would make the denominator of the \n" ); document.write( "original equation zero. \n" ); document.write( "----------- \n" ); document.write( "Final Answer: No solutions \n" ); document.write( "================== \n" ); document.write( " \n" ); document.write( "5/(x+6) + 2/(x^2+7x+6) = 3/(x+1)\r \n" ); document.write( "\n" ); document.write( "Multiply thru by (x+6)(x+1) which is the same as x^2+7x+6 \n" ); document.write( "--------- \n" ); document.write( "5(x+1) + 2 = 3(x+6) \n" ); document.write( "5x+5+2 = 3x+18 \n" ); document.write( "5x+7 = 3x+18 \n" ); document.write( "2x = 11 \n" ); document.write( "x= 11/2 \n" ); document.write( "-------- \n" ); document.write( "Cheers, \n" ); document.write( "Stan H.\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
