5. Let A = a22 a23 be an upper triangular matrix such that the elements on 0 A33. all a12 a13 0 0 X₁ the main diagonal are non-zero and let x = x₂ (a) Solve the equations Ax=0 by starting at the equation for x, and working -- backwards towards the equation for x₁. (So: the equation for x3 is a33x3 = 0⇒x3=0, The equation for x₂ is a22x₂ + a23x3 = 0 and we know that x3 = 0, so x₂ = 0, etc.) 0 (b) Use the same method as in (a) to solve the equations Ax= 1 and Ax= 0 -8- (c) Use the results from (a) and (b) to deduce the inverse matrix A¹.
