Solve the following systems of equations. To unlock puzzle three find the product of each solution (ordered pair -x and y value)
and then find the mean of all five products.
(3x + y = 4
1)
12x - y = 6
2)
(2x + y = -3
13x + 2y = -8
3)
(7x - 4y = -7
5x + y = 22
4)
-x + 9y = -5
x - 5y = 1
5)
( x - y = -4
1-2x + 3y = 6
