Question

Please select the best answer and click submit Solve kx-4=9 for x

Answer 1

Answer:

Option B. $x = \frac{13}{k}$.

Step-by-step explanation:

The given equation is kx - 4 = 9

We will add 4 on both the sides of the equation

kx - 4 +4 = 9 +4

kx = 13

Now we will divide by k on both the sides of the equation

$\frac{1}{k}(13x) = \frac{1}{k}13$

$x = \frac{13}{k}$

Therefore Option B x = 13/k is the right answer.

Answer 2

Answer:

$\large\boxed{B.\ x=\dfrac{13}{k}}$

Step-by-step explanation:

$kx-4=9\qquad\text{add 4 to both sides}\\\\kx=13\qquad\text{divide both sides by }\ k\neq0\\\\x=\dfrac{13}{k}$
