We can just substitute y = 4x+1 in the second equation.
We know the value of x, substitute x in any equations to get the y-value.
The value of y is 3 and the value of x is 0.5 aka 1/2
Since you want the solution as a point then It's below here.

Answer:
Step-by-step explanation:
Leaving leap years, a year contains 365 days.
For a group of 100 people, each person is independent of the other and probability of any day being his birthday has a chance of
a) Probability that exactly 3 people have same birthday =
Each day is independent of the other
And hence no of days having exactly 3 persons birthday out of 100 persons is binomial with n = 365 and p =
Expected value of days = np =
b) Distinct birthdays is binomail with p =1/365 and n = 365
Hence
expected value = np =1
