Answer:


X =\left[\begin{array}{cc}-2 &-11\\4 &-3\end{array}\right]

Explanation:

Given


R =\left[\begin{array}{cc}0&3\\-4&5\end{array}\right]


S =\left[\begin{array}{cc}-2&-8\\0&2\end{array}\right]


X + R = S

Required

Find X


X + R = S

Make X the subject


X = S - R

Substitute values for S and R


X =\left[\begin{array}{cc}-2&-8\\0&2\end{array}\right] - \left[\begin{array}{cc}0&3\\-4&5\end{array}\right]

This can be rewritten as:


X =\left[\begin{array}{cc}-2 -0 &-8 - 3\\0 - (-4) &2 - 5\end{array}\right]


X =\left[\begin{array}{cc}-2 &-11\\4 &-3\end{array}\right]
