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

Solution:

In the given problem , we have to find the value of a in terms of k and b.

Given equation k = 4a + 9ab

Let us take a as common from both the terms of rhs,

k = a(4 + 9b)

After cross multiply, we get

a = k/(4 + 9b)

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

Summary:

Solving the equation k = 4a + 9ab for a we have a = k/(4 + 9b)
