The above answer does not have three CONSECUTIVE even integers.
To find them, you would express it as
X + (X+2) + (X+4) = 84
3X + 6 = 84
3X = 78
X = 26, X+2 = 28, X+4 = 30
26 + 28 + 30 = 84
Three consecutive even integers that equal 84 are 26, 28, & 30

Or, you could realize the average of the three consecutive integers is the same as the middle one, and is the same as the sum divided by 3.
84/3 = 28, so 28 is the middle one.

However, they ARE asking for all three integers. Your method would work, as 3x = 84; however, for the answer, you would then have to express x-2, x, and x+2

It's 28 + 28 + 28 = 84
