Question

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

Answer 1

Answer:

C

Step-by-step explanation:

So we have the equation:

$\frac{x-2}{5}=k$

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:

$\frac{x-2}{5}=-4$

And now, we just have to solve for x.

Let's multiply both sides by 5:

$(5)\frac{x-2}{5}=5(-4)$

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!
