The idea is that a regular equation is simply a statement that two quantities are the same; this statement may, or may not, be true - or it may depend on the value of the variables. For example, x + 2 = 5 is true, only if x is replaced with 3. An "identity" is an equation that is true for any value of the variables.

Why are the equations w-x plus xw and w plus x-xw called identities?
w - x + x = wand w + x - x = w are true for all values of w and x and that is why they are called identities.
Why are the equation w-x plus xw and w plus x-xw called identities?
w - x + x = wand w + x - x = w are true for all values of w and x and that is why they are called identities.
Why are the equations w minus x plus x equals w and w plus x minus x equals w called Identities?
They are identities because they are true for ALL values of w and x.

Unfortunately, limitations of the browser used by Answers.com means that we cannot see most symbols. It is therefore impossible to give a proper answer to your question. Please resubmit your question spelling out the symbols as "plus", "minus", "times", "equals", etc. There are no visible symbols after the second x, for example. More important, there are no equals signs and so there is nothing that could be an identity.

Simplify boolean algebra equation abc plus a'b'c' plus a'b'c plus a'bc plus ab'c' plus abc'?
In this case you want to group the terms so they have at least two terms in common. First step group and rewrite it: abc + a'bc + a'b'c' + a'b'c + ab'c' + abc' = Use the rule Identities x(y+z)=xy+xz: bc(a+a') + a'b'(c'+c) + ac'(b'+b) = Use the rule Identities x+x'=1: bc (1) + a'b'(1) + ac'(1) = Use the rule Identities x(1) = x: bc+a'b'+ac'
