Take out a common factor between 3x and kx. That means use the distributive law to get what you normally would start with.

x(k + 3) = 4

Now divide by k + 3

x = 4/(k + 3)

That's as much as you can do with this question.

The given algebraic expression is made up of a constant(x) and a variable.

Given that:

kx + 3x = 4

the first thing to do is to identify the common like terms.

Here, kx and 3x are the two common terms.

Let's factorize out x from the two terms, by doing so, we have:

x(k + 3) = 4

The next thing to do is to divide both sides by (k +3) since we are solving for x.

[tex]\mathbf{\dfrac{x(k+3)}{(k+3)}= \dfrac{4}{(k+3)}}[/tex]

[tex]\mathbf{x= \dfrac{4}{(k+3)}}[/tex]

Therefore, we can conclude that the solution for (x) to the simplest term is:

[tex]\mathbf{ \dfrac{4}{(k+3)}}[/tex]
