Question

Write the systems of equations described by each augment matrix

Answer 1

EXPLANATION

Given the Matrix:

`\begin{bmatrix}{2} & {-4} & {4} \\ {1} & {2} & {11} \\ {} & {} & {}\end{bmatrix}`

Our system of equations will be:

`\begin{bmatrix}{x1} & {y2} & {c1} \\ {x2} & {y2} & {c1} \\ {} & {} & {}\end{bmatrix}`

(1) x1 + y1 = c1

(2) x2 + y2 = c2

So, replacing values of given Matrix, this will give us:

Equation (1): 2x -4y = 4

Equation (2): x +2y = 11
