Algebra.Com's Answer #83835 by bucky(2189) ![]() You can put this solution on YOUR website! Since the two integers are consecutive, if we call the first one X, then the second one \n" ); document.write( "will be 1 number bigger, so it will be X + 1. \n" ); document.write( ". \n" ); document.write( "One-half of the second integer is (1/2)*(X + 1). If you subtract this from the first integer \n" ); document.write( "X the answer is to be 2. In equation form this is: \n" ); document.write( ". \n" ); document.write( "X - (1/2)(X + 1) = 2 \n" ); document.write( ". \n" ); document.write( "You can get rid of the fraction (1/2) by multiplying both sides of this equation (all terms) by \n" ); document.write( "2 and the equation becomes: \n" ); document.write( ". \n" ); document.write( "2X - (X + 1) = 4 \n" ); document.write( ". \n" ); document.write( "Since the parentheses are preceded by a minus sign, you can remove the parentheses if \n" ); document.write( "you change the signs of the terms inside the parentheses. Applying this rule results in: \n" ); document.write( ". \n" ); document.write( "2X - X - 1 = 4 \n" ); document.write( ". \n" ); document.write( "Get rid of the -1 on the left side by adding +1 to both sides and you have: \n" ); document.write( ". \n" ); document.write( "2X - X = 5 \n" ); document.write( ". \n" ); document.write( "Combine the two terms on the left side and you have: \n" ); document.write( ". \n" ); document.write( "X = 5 \n" ); document.write( ". \n" ); document.write( "This tells you that the two consecutive integers are 5 and 6 \n" ); document.write( ". \n" ); document.write( "Check. If you take half of the second integer you get 3. And if you subtract that from \n" ); document.write( "the first integer you get 5 - 3 = 2 ... which is just what the problem required. Therefore, \n" ); document.write( "the answer that the integers are 5 and 6 checks out. \n" ); document.write( ". \n" ); document.write( "Hope this helps you to understand how to work the problem. \n" ); document.write( ". \n" ); document.write( " \n" ); document.write( " |
