Question

HELPPPPPPPPPP Add & subtract matrices .....

PLZ GIVE THE ANSWER .. THANKSSSSS .

Answer 1

For this case, we must subtract the given matrices, for this we subtract term to term.

So, we have:

Equal signs are added and the same sign equals:

$\left[\begin{array}{ccc}-2-2\\-2-1\\1-1\end{array}\right]$=

$\left[\begin{array}{ccc}-4\\-3\\0\end{array}\right]$

ANswer:

$\left[\begin{array}{ccc}-4\\-3\\0\end{array}\right]$

Answer 2

Answer:

$\left[\begin{array}{ccc}-4\\-3\\0\end{array}\right]$

Step-by-step explanation:

Given in the question two matrix, a matrix can only be added to (or subtracted from) another matrix if the two matrices have the same dimensions.

Here the dimensions are 3x1 and 3x1 .

$\left[\begin{array}{ccc}-2\\-2\\1\end{array}\right]$-$\left[\begin{array}{ccc}-2\\1\\1\end{array}\right]$

To subtract two matrices, just subtract the corresponding entries

=$\left[\begin{array}{ccc}-2-2\\-2-1\\1-1\end{array}\right]$

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