I have to simplify this Boolean expression but i quite found it difficult since don't know in which order had to start with. the expression is:

(x iff y) or (y iff z) if x

found it little complicated to simplify since i don't know the order do I have to write it like:

((x iff y) or (y iff z)) if x

or:

(x iff y) or ((y iff z) if x)

if you can give me a spot on this section of Boolean algebra. and I really will appreciate it if you gave me steps on how to simplify it. and had to say that I already tried a lot, solved a lot, tried wolfram alpha and others too even compared the results using truth tables but get different results and didn't know the right one from them. thanks in advance for your helping
