Algebra.Com's Answer #79999 by bucky(2189)![]() ![]() ![]() You can put this solution on YOUR website! Let x be the unknown number \n" ); document.write( ". \n" ); document.write( "Then twice the number is 2x \n" ); document.write( ". \n" ); document.write( "Five times the number is 5x \n" ); document.write( ". \n" ); document.write( "60 more than five times the number is 60 + 5x \n" ); document.write( ". \n" ); document.write( "The equality in the problem is that 2x is equal to 60 + 5x and in equation form this can \n" ); document.write( "be written: \n" ); document.write( ". \n" ); document.write( "2x = 60 + 5x \n" ); document.write( ". \n" ); document.write( "Get rid of the 5x on the right side by subtracting 5x from both sides to get: \n" ); document.write( ". \n" ); document.write( "-3x = 60 \n" ); document.write( ". \n" ); document.write( "Solve for x by dividing both sides of this equation by -3 to arrive at: \n" ); document.write( ". \n" ); document.write( "x = 60/(-3) = -20 \n" ); document.write( ". \n" ); document.write( "The unknown number is -20. \n" ); document.write( ". \n" ); document.write( "Twice this number is -40 and five times this number is -100. Is -40 really 60 more than -100? \n" ); document.write( "Yes it is because on a number scale -40 is 60 units to the right of -100. \n" ); document.write( ". \n" ); document.write( "Hope this helps you to understand the problem a little better. \n" ); document.write( ". \n" ); document.write( " |
