Unformatted text preview: A1 or C1 . (d) Show that E1 does not exist. (e) Suppose we are given the matrix equation, EX = (AB) where X = x y . First, write out the complete expression for EX = (AB). Then rewrite this as a system of linear equations. 4) Using matrix equations, solve the following systems of equations. (a) Find the solution for this system. 4 xy = 3 2 x + 5 y =9 (b) Find the solution for this system.9 x + 4 y =136 x + 3 y = 1 1...
