Question

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

Answer 1

`\large\boxed{B.\ x=(13)/(k)}`

Explanation:

`kx-4=9\qquad\text{add 4 to both sides}\\\\kx=13\qquad\text{divide both sides by }\ k\\eq0\\\\x=(13)/(k)`

Answer 2

Option B.
`x = (13)/(k)`.

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

`(1)/(k)(13x) = (1)/(k)13`

`x = (13)/(k)`

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