Here, we are required to write a matrix to represent the system of equations;
The correct answer is Choice A.
To generate a matrix to represent the system bof equations,the coefficients of each variables are filled into the matrix as the elements of the matrix accordingly;
As such,
- On the first column of the matrix, the coefficients of variable, a in both equations are filled accordingly,
- i.e 2 and 1.
- On the second column of the matrix, the coefficients of variable, b in both equations are filled accordingly,
- i.e -3 and 1.
However, on the last column of the matrix;
- The constants in both equations are filled accordingly too, i.e 6 and 2
Therefore, since Choice A follows the guide above, it is the required matrix to represent the system of equations.
