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