Algebra.Com's Answer #72346 by bucky(2189)![]() ![]() ![]() You can put this solution on YOUR website! Let x be the smallest of the three consecutive odd integers. The next odd integer is 2 above \n" ); document.write( "that or x + 2, and the next odd integer is 2 above that or x + 2 + 2 which is x + 4. So the \n" ); document.write( "three consecutive odd integers are x, x + 2, and x + 4. \n" ); document.write( ". \n" ); document.write( "If you add these three consecutive odd integers together the sum is to equal the smallest \n" ); document.write( "of these odd integers ... that is to say the sum of the three integers is to equal x. In equation \n" ); document.write( "form this becomes: \n" ); document.write( ". \n" ); document.write( "x + x + 2 + x + 4 = x \n" ); document.write( ". \n" ); document.write( "On the left side, add the x terms and then add the numbers. The result is: \n" ); document.write( ". \n" ); document.write( "3x + 6 = x \n" ); document.write( ". \n" ); document.write( "Get rid of the x on the right side by subtracting x from both sides to get: \n" ); document.write( ". \n" ); document.write( "2x + 6 = 0 \n" ); document.write( ". \n" ); document.write( "Get rid of the 6 on the left side by subtracting 6 from both sides to change the equation to: \n" ); document.write( ". \n" ); document.write( "2x = -6 \n" ); document.write( ". \n" ); document.write( "Solve for x by dividing both sides by 2 and you get: \n" ); document.write( ". \n" ); document.write( "x = -6/2 = -3 \n" ); document.write( ". \n" ); document.write( "So x, the smallest of the three consecutive odd integers is -3. The next bigger odd integer \n" ); document.write( "is found by adding 2 to get -1. And the final consecutive odd integer is found by adding \n" ); document.write( "2 to -1 to get +1. So the three consecutive odd integers are -3, -1, +1. \n" ); document.write( ". \n" ); document.write( "If you add these integers you get -3 and that sum is the same as the smallest of the consecutive \n" ); document.write( "odd integers which is x = -3. The answer checks. \n" ); document.write( ". \n" ); document.write( "Hope this helps you to understand the problem. \n" ); document.write( ". \n" ); document.write( " \n" ); document.write( " |
