Problem 2: Solve the linear system of equations 9.1x1+6.6x2 = 2.0 4.621 + 3.3r2 = 1.0 Ax=b 9.1 6.6) (2.0 4.6 3.3 21.0 using the restrictions as outlined below. Use the gaussian elimination algorithm in which the first step is to eliminate xi from the second equation by adding a multiple of the first equation 1. Use only 2 digit arithmetic. That is: round every intermediate result to 2 significant digits. Show all your intermediate results, including the equations or matrix forms obtained when you have eliminated one variable. 2. Repeat the preceding but using "exact" arithmetic: using as many digits as vour calculator will give you. If you use a computer, use the standard built-in floating point (single or double 3. Using "exact" arithmetic, plug both answers into the original equations to compute the two residuals r = b-Ax
