for this problem they give you the Kw of water and it is 2.1 x 10^-14 and you have to find the hydronium and hydroxide concentration. in the answer explanation they made the two equal is it because it's water that hydronium and hydroxide equal?

Because you know that the solution is neutral water (pH ~7), the hydronium and hydroxide concentrations must equal each other and balance each other out.
