8. The correct answer is (D). To answer the question, there’s no way around doing some
pencil-work. You need to solve for x in each equation, then square it. Let’s start with
statement (2), which is a bit easier to work with:
2x
1
5
5
1
2x
5 24
x
5 22

Now let’s tackle statement (1), which presents a more complex equation:
~x
2
3!
2
5 ~x
1
7!
2
~x
2
3!~x
23! 5 ~x

6x

9
5
x
2
1
14x

49
20x
5 240
As you can see, both statements provide essentially the same information about x. With
either statement, you can answer the question. Hence the correct answer is choice (D).
