WebMar 27, 2024 · You set up the augmented matrix and row reduce to get the solution. Thus the matrix you must row reduce is The reduced row-echelon form is [1 0 − 5 4 0 0 1 1 2 0 0 0 0 0] and so the solution is any vector of the form [ 5 4s − 1 2s s] = s[ 5 4 − 1 2 1] where s ∈ R. Webin non system cases, think about if you have just y = mx+b or y equals a number. if you have a number instead of y (and m of course) you can solve for x, while having y there makes it only so you can find a function you can graph. Let …
