a. A' means the complement with respect to Z? If so, then
To know A' you need to write all the elements in Z that are not in A.

b. All the subsets of B, is knowed as P(B),

c.
(Add to A the elements of B, or equivalently add to B the elements of A)
d.
express informally speaking the elements that have in common, but there is no element in common, so

6(a+3) = 18 + 6a
Open the parenthesis and distribute
6a + 18 = 18 + 6a
Subtract both sides by 18
6a = 6a
Subtract both sides by 6a
0 = 0
Any value of "a" will satisfy this equation.
