Elitist

Explanation:

Elitist view of the interest group influence in policy making believe that the society is essentially ruled by a small elite group that control the laws from behind the scene, even within a democratic country.

In United States for example,

Rich business owners have the power to form interest groups and give huge amount of 'Donations' to a certain political candidate.  When that specific candidate is elected to the government that candidate will focus on the effort to pass a law that will be beneficial for the donators. This is one way they could control the government from behind the scene.

u = 30

continuing your method

= +

subtract from both sides

= - thus

= -

= ⇒ u = 30
