I think you would divide 72 by 3 to get 24i think you would divide 72 by 3 to get 24 then subtract 4 from 24 to get 20.
Therefore 1 book cost $20 and the other cost $52. I may be wrong though.
If we substitute z = 2 - x - y in the last 2 equations it simplifies to 2 equations in x and y:=
x^2 + y^2 + xy - 2x - 2y = 5 and
-x^2 - y^2 - xy + 2x + 2y = -5
if we add these we get 0 = 0 so there are infinite solutions
Let's begin by defining the key terminologies:
The degree of a polynomial simply refers to the term with the highest exponent in a polynomial
For example:
