To solve this expression, we can first simplify it by multiplying out the terms:

4(7b + 4a) = 28b + 16a
b(7b - 4a) = 7b^2 - 4ab

Now, we can divide the two expressions:

(28b + 16a) / (7b^2 - 4ab)

This expression cannot be simplified further without knowing specific values for variables a and b. So, the final result is:

(28b + 16a) / (7b^2 - 4ab)
