The solution of the given equations is: (-1.5, 1.5)
Step-by-step explanation:
Linear equation usually represents a straight line. When a system of two liner equations is given, the point of intersection of lines represented by both equations is the solution of the system of equations.
We will plot the lines of both equations and find their point of intersection (Picture Attached)
We can see in the picture that two lines intersect at (-1.5, 1.5)
Hence,
The solution of the given equations is: (-1.5, 1.5)

To make this a fraction, let's put

. We can divide both top and bottom by 6, leaving us with

. This is as far as we can reduce it, making it your answer. I hope this helps!
Answer:
Step-by-step explanation:
The geometric distribution represents "the number of failures before you get a success in a series of Bernoulli trials. This discrete probability distribution is represented by the probability density function:"
Let X the random variable that measures the number os trials until the first success, we know that X follows this distribution:
In order to find the expected value E(1/X) we need to find this sum:

Lets consider the following series:
And let's assume that this series is a power series with b a number between (0,1). If we apply integration of this series we have this:
(a)
On the last step we assume that
and
, then the integral on the left part of equation (a) would be 1. And we have:

And for the next step we have:

And with this we have the requiered proof.
And since
we have that:
