Respuesta :

K = 4a + 9ab
K = a (4 + 9b)
K / (4 + 9B) = a
ANSWER

[tex] a = \frac{k}{(4 + 9b)} [/tex]

EXPLANATION

We have the equation,

[tex]k = 4a + 9ab[/tex]

To solve for [tex]a[/tex]
means, we should isolate [tex]a[/tex] on one side of the equation so that any other variable or constant term will also be at the other side of the equation.

Let us factor [tex]a[/tex]
out of the right hand side of the equation to obtain,

[tex]k = a(4 + 9b)[/tex]

We now divide both sides of the equation by

[tex](4 + 9b)[/tex]

Therefore;

[tex] \Rightarrow \: \frac{k}{(4 + 9b)} = a[/tex]
