Thxx btw

Answer 10

3. a)

\[(F\cup G)\setminus X = E\\
\qquad \text{Plugging in the sets}\\
\left(\Big\{a,1,\{1\},\Big\}\cup \Big\{a,2,\{2\}\Big\}\right)\setminus X
= \Big\{1,\{1\},2,\{2\}\Big\}\\
\qquad \text{Taking the union}\\
\Big\{a,1,\{1\},2,\{2\}\Big\}\setminus X
= \Big\{1,\{1\},2,\{2\}\Big\}\\
\]
The equation now reads:
"Some set, if we take away the set X,
will be equal to some other set."

You have to find X,
i.e. the set of all the elements that must be taken from the set on the left,
for it to be equal to the set on the right.
