Solve the following systems of equations using MATLAB You will need to work out A and b for each system a. 3x + y = 11 x + 4y = 11 Ax = b x = Ab Once you have identified A and b you can solve in MATLAB x = inv (A) *b or x = A\b or x = A^ (-1) *b Note that if this is the solution A*x should equal b b. 2x + 3y 2z = 3 x- 2y + 4z = 0 2x 3y + z = 1 Once you have identified A and b you can solve in MATLAB x = A\b Note that if this is the solution A*x should equal b What does A*inv(A) do? Does it work for non-square matrices?
