Question

Please help
X-2
If = k and k = -4, what is the value of x?
5

Answer 1

C

Explanation:

So we have the equation:

`(x-2)/(5)=k`

And we want to find the value of x such that k is -4.

To do so, we can substitute -4 for k and then solve for x.

So, substitute -4 for k:

`(x-2)/(5)=-4`

And now, we just have to solve for x.

Let's multiply both sides by 5:

`(5)(x-2)/(5)=5(-4)`

The left side cancels. Multiply on the right:

`x-2=-20`

Now, let's add 2 to both sides:

`(x-2)+2=(-20)+2`

The left side cancels again. Add on the right:

`x=-18`

Therefore, the value of x is -18.

Our answer is C.

And we're done!
