Answer 1

The resulting matrix of the row operation is given as follows:

$R = \left[\begin{array}{ccc}7&4.5&-6\\-6&-3&12\end{array}\right]$

How to find the resulting matrix?

We apply the row operation on the original matrix, given as follows:

$A = \left[\begin{array}{ccc}4&3&0\\-6&-3&12\end{array}\right]$

The operation is given by:

$R_1 = R_1 - 0.5R_2$

That is, applying to each element, we have that:

• 4 - 0.5(-6) = 7.

• 3 - 0.5(-3) = 4.5.

• 0 - 0.5(12) = -6.

Hence the resulting matrix is:

$R = \left[\begin{array}{ccc}7&4.5&-6\\-6&-3&12\end{array}\right]$
