EXPLANATION
Given the Matrix:
[tex]\begin{bmatrix}{2} & {-4} & {4} \\ {1} & {2} & {11} \\ {} & {} & {}\end{bmatrix}[/tex]Our system of equations will be:
[tex]\begin{bmatrix}{x1} & {y2} & {c1} \\ {x2} & {y2} & {c1} \\ {} & {} & {}\end{bmatrix}[/tex](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
