QuestionSubtract 3 times the first row from the matrix. Find the new first row: [21]3[10]\left[\begin{array}{cc}-2 & 1\end{array}\right]-3\left[\begin{array}{cc}1 & 0\end{array}\right]

Studdy Solution
Replace the first row of the original matrix with the result of the subtraction.
[4232]\left[\begin{array}{cc} 4 & -2 \\ 3 &2\end{array}\right] So, the correct matrix after applying the operation is[4232]\left[\begin{array}{cc} 4 & -2 \\ 3 &2\end{array}\right]
