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]

<h3>How to find the resulting matrix?</h3>

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]
