1. Show that the following relationships exist, given the following sets for X and Y.
X = {1, 5, 10} Y = {10, 20, 30}
(a) S X + Y = S Y + S X
(b) S a X = a S X where a = 5.
(c) S Y2 ( S Y)2
(d) S S X@Y = S X S Y
(e) S 1/N Where N = 5.
2. Solve the following system of two equations and two unknowns using matrix notation and mathematics. Then show the same answer using substitution.
10X+ 5Y = 50
5X-5Y = 10
