Solve each system using matrix notation. Express the solution using vectors.
a) 3x +6y = 18
x + 2y = 6
b) 2b + b - c = 2
2a + c = 3
a - b = 0

a = x 1 = 1 5 , b = x 2 = 1 5 , c = x 3 = 13 5
so if you plug in those values into the given equations, 2b +b - c = 2
2a + c = 3 and a - b =0 , you will see that such found values for a, b, and conly work for the last equation, a-b = 0.
