Algebra.Com's Answer #810561 by greenestamps(13203)![]() ![]() You can put this solution on YOUR website! \n" ); document.write( "While it is often the case in problems with consecutive even integers that using x-2, x, and x+2 for the three integers makes the algebra needed to solve the problem easier, it does not look that way for this problem. \n" ); document.write( "A quick mental solution could go like this: \n" ); document.write( "The third integer is 4 more than the first; so if the sum of the third and twice the first is 268,246 then three times the first is 268,246-4=268,242. So the smallest of the integers is 268,242/3 = 89414. \n" ); document.write( "ANSWERS: 89,414; 89,416; and 89,418 \n" ); document.write( "The same solution using formal algebra would look like this: \n" ); document.write( "2(x)+(x+4) = 268246 \n" ); document.write( "3x+4 = 268246 \n" ); document.write( "3x=268242 \n" ); document.write( "x=268242/3 = 89414 \n" ); document.write( "89414, 89416, and 89418 \n" ); document.write( " \n" ); document.write( " |
