Answer» plz make me brainlistExplanation:This vignette ILLUSTRATES the IDEAS BEHIND solving systems of linear equations of the form Ax=bAx=b whereAA is an m×nm×n matrix of coefficients for mm equations in nn unknownsxx is an n×1n×1 vector unknowns, x1,x2,…xnx1,x2,…xnbb is an m×1m×1 vector of constants, the “right-hand sides” of the equationsThe GENERAL conditions for solutions are:the equations are consistent (solutions EXIST) if r(A|b)=r(A)r(A|b)=r(A)the solution is unique if r(A|b)=r(A)=nr(A|b)=r(A)=nthe solution is underdetermined if r(A|b)=r(A) |
