He thinks the spirit of parties are the worst because, “It exists under different shapes in all governments, more or less stifled, controlled, or repressed; but, in those of the popular form, it is seen in its greatest rankness, and is truly their worst enemy.” A government with great power is prone to abuse it, a government needs to distribute the powers so no part of the government is strong enough to over power the other.

1.3x - 2 - (3.3x + 5) = 2x + 1

-7 = 4x + 1

-8 = 4x

x = -2
