Solve the system of equations 0.2072a +0.4244b: = 1.4762 0.2081a0.4247b = 0.9327 by only keeping the first 4 digits after the decimal place. (So chopping and not rounding) Compute the residue error for your solution, that is take your two approximations for a and b, and , and measure the exact relative error of 1.4762 0.9327 and where 0.2072 +0.42446 = 0.2081+0.42476 = .
