Algebra.Com's Answer #46761 by tanimachatterjee(60)![]() ![]() ![]() You can put this solution on YOUR website! 9/x-5 - 1 = 8/x+5 \n" ); document.write( "or [9-(x-5)]/x-5 = 8/x+5 \n" ); document.write( "or 14-x/x-5 = 8/x+5 \n" ); document.write( "or (14-x)(x+5) = 8(x-5)[cross multiplications] \n" ); document.write( "or 14x + 70 -x2 -5x = 8x - 40 \n" ); document.write( "or -x2 +14x -5x -8x +70 +40 =0 \n" ); document.write( "or -x2 + x + 110 =0 \n" ); document.write( "or x2 -x -110 = 0[multiplying both sides by -1] \n" ); document.write( "or x2 -11x +10x -110 =0[middle term breaking] \n" ); document.write( "or x(x -11) +10(x-11)=0 \n" ); document.write( "or (x+10)(x-11)=0 \n" ); document.write( " therefore either x+10=0 , x=-10 \n" ); document.write( " or x-11=0 ,x=11 \n" ); document.write( " \n" ); document.write( " |
