Algebra.Com's Answer #76030 by HyperBrain(694)![]() ![]() ![]() You can put this solution on YOUR website! Let x=the number\r \n" ); document.write( "\n" ); document.write( "The first part says,\"Four times...\"\r \n" ); document.write( "\n" ); document.write( "So automatically write,\r \n" ); document.write( "\n" ); document.write( "4*\r \n" ); document.write( "\n" ); document.write( "Continuing,\"Four times the 'difference of a number and one'...\". Difference of a number and one is similar to th expression, x-1, connecting it to 4*,\r \n" ); document.write( "\n" ); document.write( "4*(x-1)\r \n" ); document.write( "\n" ); document.write( "The next words are,\"is equal to\". This signifies the equal sign. So,\r \n" ); document.write( "\n" ); document.write( "4*(x-1)= \n" ); document.write( " \n" ); document.write( "The next part:six times the sum of the number and three--same as 6*(x+3)\r \n" ); document.write( "\n" ); document.write( "Then,\r \n" ); document.write( "\n" ); document.write( "4*(x-1)=6*(x+3) \n" ); document.write( " 4x-4=6x+18 \n" ); document.write( " 4x=6x+22 \n" ); document.write( " -2x=22 \n" ); document.write( " x=-11\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Therefore, th number is -11! \n" ); document.write( " |
