I'm not sure how to solve it and put it in an equation!

Let 2x be the least. Then the next 3 even integers are 2x+2, 2x+4, 2x+6
So, add them up:
2x + 2x+2 + 2x+4 + 2x+6 = 2x
Now solve for x, and ...
Extra credit: We used 2x to make sure it was an even number. What would have happened if we had just used x instead?
