value of x is
and value of y is 
Step-by-step explanation:
We need to find Which expression could be substituted for y in the second equation to find the value of x
The given equations are:

For putting value of y in second equation, we will find from equation 1
From equation 1:

Putting value of y i.e y=10+2x in equation (2) to find value of x

So, now finding value of y by putting value of x= -29/4 in eq(1)

So, value of x is
and value of y is

Sum of probabilities in a discrete probability distribution is 1.
Step-by-step explanation:
The sum of the probabilities in a probability distribution is always 1.
A probability distribution is a collection of probabilities that defines the likelihood of observing all of the various outcomes of an event or experiment. Based on this definition, a probability distribution has two important properties that are always true:
Each probability in the distribution must be of a value between 0 and 1.
The sum of all the probabilities in the distribution must be equal to 1.
