Algebra.Com's Answer #98892 by vleith(2983)![]() ![]() ![]() You can put this solution on YOUR website! You have more than a clue. Don't fret, You are part way there already.\r \n" ); document.write( "\n" ); document.write( "Your solution uses the number n. But there is nothing that ensures that 'n' is even. So let's use a different set of numbers. \n" ); document.write( "Let's assume n is even, if so, then n/2 is still an integer. \n" ); document.write( "Our three numbers will be n/2, (n+4)/2 and (n+8)/2\r \n" ); document.write( "\n" ); document.write( "Add in one more given \" four times the middle integer is equal to two less than the sum of the first and third integers.\"\r \n" ); document.write( "\n" ); document.write( "so \n" ); document.write( "Left left side is four times the middle number.
