Algebra.Com's Answer #411121 by kevwill(135)![]() ![]() You can put this solution on YOUR website! Let x be the number we're looking for. Then, from the problem statement: \n" ); document.write( "8*(x-8) = 6*(x-6) \n" ); document.write( "Expanding: \n" ); document.write( "8x - 64 = 6x - 36 \n" ); document.write( "Subtracting 6x - 64 from both sides: \n" ); document.write( "8x - 64 - (6x - 64) = 6x - 36 - (6x - 64) \n" ); document.write( "8x - 64 - 6x + 64 = 6x - 36 - 6x + 64 \n" ); document.write( "2x = 18 \n" ); document.write( "x = 14 \n" ); document.write( "Checking: \n" ); document.write( "8*(14 - 8) = 8*6 = 48 \n" ); document.write( "6*(14 - 6) = 6*8 = 48\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
