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.

Step-by-step explanation:

Set them equal to each other since they're both equal to y

3x-5=.5x +5

add 5 to both sides

3x=.5x+10

subtract .5x from both sides

2.5x=10

divide both sides by 2.5

x= 4
