Question

HELPPPPPPPPPP Add & subtract matrices .....

PLZ GIVE THE ANSWER .. THANKSSSSS .

Answer 1

For this case we must add the following matrices:

`\left[\begin{array}{ccc}3&1\\0&-2\end{array}\right]`

And

`\left[\begin{array}{ccc}4&0\\3&-1\end{array}\right]`

Adding up:

`\left[\begin{array}{ccc}3+4&1+0\\0+3&-2+(-1)\end{array}\right]=\\\left[\begin{array}{ccc}3+4&1+0\\0+3&-2-1\end{array}\right]=\\\left[\begin{array}{ccc}7&1\\3&-3\end{array}\right]`

Answer:

`\left[\begin{array}{ccc}7&1\\3&-3\end{array}\right]`

Answer 2

`\left[\begin{array}{cc}7&1\\3&-3\end{array}\right]`

Explanation:

We simply add entry of each column of matrix 1 with its corresponding column entry of second matrix.

`= \left[\begin{array}{cc}3&1\\0&-2\end{array}\right] + \left[\begin{array}{cc}4&0\\3&-1\end{array}\right]\\= \left[\begin{array}{cc}3+4&1+0\\0+3&-2+(-1)\end{array}\right]\\=\left[\begin{array}{cc}7&1\\3&-3\end{array}\right]`
