    why is the denominator 3? does it have something to do with the number of equations involved? or something else?

    I understood what was going on until the (a+b+c)/3 so if a+b+c =14 is our average 14/3?

    Thank you @maheshmeghwal9 :) @UsukiDoll what I understand about 2 is that a,b and c are occurring twice so adding them will give (2a + 2b + 2c) taking out common "2" will give 2(a + b + c) :D
