Solve the equation for a. K = 4a + 9ab

Given equation is K = 4a + 9ab

Now we solve for 'a'. We need to get 'a' alone

We factor out 'a' from the right hand side

K = 4a + 9ab

K = a (4+9b)

Now we divide the equation both sides by 4+9b

\frac{K}{4+9b} = a \frac{(4+9b)}{(4+9b)}

\frac{K}{(4+9b)} = a

So a=\frac{K}{(4+9b)}
