# Weighing up the positives and the negatives

$\underbrace{\pm (x-1) \pm (x-1) \cdots \pm (x-1) \pm (x-1)}_{“\pm (x-1)" \text{ appears 2018 times}} = 2018$

On the left side of the equation, "$\pm (x-1)$" repeats 2018 times.

How many integer solutions of $x$ are there?

Note: The "$\pm$" symbols are independent of one another.
