Solve for x.

3x - 8x + 2 = 17

X=

Is it greater than or less than7*3_9*2

Arational number that is equivalent to -20/4?

Let x have probability generating function gx (s) and let un generating function u(s) of the sequence uo, u1, satisfies p(x > n). show that the (1- s)u(s) = 1 - gx(s), whenever the series defining these generating functions converge.
