Question

Solve the equation for a.

K = 4a + 9ab

Answer 1

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

Answer 2

ANSWER


`a = (k)/((4 + 9b))`

Step-by-step explanation

We have the equation,


`k = 4a + 9ab`

To solve for
`a`
means, we should isolate
`a` 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
`a`
out of the right hand side of the equation to obtain,


`k = a(4 + 9b)`

We now divide both sides of the equation by


`(4 + 9b)`

Therefore;


`\Rightarrow \: (k)/((4 + 9b)) = a`
