Solving Linear Equations \(A\mathbf{x}=\mathbf{b}\)

Gaussian elimination and Gauss–Jordan on one page. Build the elimination yourself — circled pivots, your multipliers, your rows — down to the echelon form, then on to the reduced form. Then solve full systems, catch the singular cases, and invert matrices with \([\,A\,|\,I\,]\).
