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

shepuryov [24]

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.
