Question

MATLAB. Awnser written questions (*) in the comments. Null, Rank, and most functions outside of rref() and disp() are not allowed! Solutions must be given manually! Elementary form means to reduce to RREF manually, without rref(). Please see other attached image for explanation

3. Start this problem in format short. Consider the linear system whose augmented matrix is 2 2 A = 3 1 -7-3 -1 0 -4 -6 6 -5 (a) Use the rref command to give the reduced row echelon form of A. Make sure your result in presented in decimals, not fractions. (b) Write the solution of the linear system which corresponds to A in decimals, not fractions. (Your "solution" is actually a decimal approximation to the solution.) (c) Give the reduced row echelon form of A in fractions rather than decimals. (d) Write the solution of the linear system which corresponds to A in fractions, not decimals.
