" Z equals a " is not a question. It's a statement of fact, so it's not looking for
an answer.
You might say that an "answer" is a pair of numbers for 'Z' and 'a' that make the
statement true. That's a good thought, but then there are an infinite number of
'answers', so it's not too useful.

What is the area under the normal curve between z equals 0.0 and z equals 2.0?
I
2+2+7=11 K?
3z equals z - 24 = -21
transitive property!
x = 24
E = 24/z or, equivalently, z = 24/E
10 z's.
mensos yo no me la seee
Add 4z to each side: 19 = -z so z = -19
