Question

Having trouble on this question.
Can anyone help?

Answer 1

Locations of X: 2, -12

Explanation:

We know that W lies at -5. To figure out where the other X's are located, you need to do -5 ± 7, since the range is 7.

So let's first try -5 + 7:

-5 + 7 = 2

The first location of X can be at 2.

Now let's try -5 - 7:

-5 - 7 = -12

The second location of X is -12.

So, the answer is that X is located at 2 and -12

Answer 2

-12, 2

Explanation:

X may be on the left of W, then X = -5 - 7 = -12

X may be on the right of W, then X = -5 + 7 = 2
