let 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....

- anonymous

How do I solve that???

- anonymous

combine like terms and isolate x

I dont know how to do that

- anonymous

x + x + x are all the same.. so add them up = 3x... same with the 4 2

- anonymous

now 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.

- anonymous

is it 18?

- anonymous

subtract 6 from both sides... thus 3x + 6 - 6 = 84 - 6

- anonymous

so 3x = 78. now you need to get rid of that 3.

- anonymous

How?

- anonymous

you can divide by the coefficient of x.. in this case 3. thus 3x/3 = 78/3

- anonymous

that will give you x = the result of 78/3

- anonymous

26? :)

- anonymous

oh wait -26?

- anonymous

yep.. now check.. 26, + 28 + 30?

- anonymous

i dont think someone can be negative years old.

- anonymous

positive 26 is NOT an option :(

- anonymous

what?

- anonymous

ooh i thought it was an age question. sorry

- anonymous

its ok :/

- anonymous

all 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.

- anonymous

and 30 doesnt work

- anonymous

Nope it was 30

- anonymous

I just got the answers

- anonymous

30+32+34 is 96?

- anonymous

good luck

- anonymous

thanks

- anonymous

30 + 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:
