Best ResponseYou've already chosen the best response.0let x be the least of these numbers... since they're consecutive, the next one would be (x+2), and the next one after that is (x+4)... since their sum is 84, you can write it out as: x + (x+2) + (x+4) = 84 now all u gotta do is solve....

Best ResponseYou've already chosen the best response.0x + x + x are all the same.. so add them up = 3x... same with the 4 2

Best ResponseYou've already chosen the best response.0now you should have 3x + 6 = 84. now you want your x term on one side of the equation and the numbers on the other side.

Best ResponseYou've already chosen the best response.0subtract 6 from both sides... thus 3x + 6  6 = 84  6

Best ResponseYou've already chosen the best response.0so 3x = 78. now you need to get rid of that 3.

Best ResponseYou've already chosen the best response.0you can divide by the coefficient of x.. in this case 3. thus 3x/3 = 78/3

Best ResponseYou've already chosen the best response.0that will give you x = the result of 78/3

Best ResponseYou've already chosen the best response.0all those negatives dont make any sense...it is .. i think.. impossible for you to take a negative number with 3 consecutive even integers and add them up to 24.

Best ResponseYou've already chosen the best response.030 + 32 + 34 \(\large \ne 84\) so the answer cannot be 30.... the answer to your question is 26... 26 + 28 + 30 = 84 looks like the correct choice is not there or the problem was mistyped... this is your orginal question: 3. The sum of three consecutive even integers is 84. What is the least of these numbers? (Points : 1) 34 30 26 30
