Question

Given. R=0 3 -4 5 and S=-2 -8 0 2. what is X if X+R=S?

Answer 1

Answer:

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

Step-by-step 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:

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

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