Question

Which one is it? Just tell me when I get the answer

Answer 1

From the given augmented matrix.

We can find the solution by taking each row one by one.

From the first row,

`\begin{gathered} 2x+(-1)* y+2z=8 \\ 2x-y+2z=8 \end{gathered}`

From the second row,

`\begin{gathered} 0* x+3* y+(-5)* z=4 \\ 3y-5z=4 \end{gathered}`

From the third row,

`\begin{gathered} 6* x+(0)* y+(-4)* z=13 \\ 6x-4z=13 \end{gathered}`

Thus, the system of equations is

`\begin{gathered} 2x-y+2z=8 \\ 3y-5z=4 \\ 6x-4z=13 \end{gathered}`

Therefore, the given option D is correct.
