Homework Statement
When finding the arithmetic mean in a system of equations is there any reason why the method that I am using is wrong?
Find the arithmetic mean of x and y in the following set of equations
Homework Equations
3x + 5y = 65 and
7x + 14y = 175
The Attempt at a Solution
I treated it as a statistics problem where x's and y's are individual units, so...
10x + 19y = 240
mean = 240/29 since mean = total sum/N My answer is 8 and 8/29
I understand that this method might not be the correct way of doing it, but if the number of units is known (10x, and not 10xy) is there any reason that this method of finding the arithmetic mean will not work.
Thank you to anyone who takes the time to look at this.
