5. Use MATLAB to solve the following system of 3 linear equations in unknowns x, y and z. 4x+3y+2z = 44 5x+5y+7x=71 X+ Z = 11 Note that these equations can be written in matrix form as A x=b, where A, x and b are the matrices: [4 3 2] A 5 5 7 [44] x= and b=71 1 0 11 Solve for x in the equation using MATLAB's "inv" function. Confirm that your x is correct by comparing the product Ax with b, that is, compute A*x-b and verify that it is close to zero. 5.
