What are the values of a, b, and c in the matrix addition below? a) a=-5 b=-9 c=-12 b) a=-14 b=15 c=-12 c) a=-14 b=-9 c=-6 d) a=-14 b=-9 c=-12

a = -14

b = -9

c = -12

Step-by-step explanation:

We have a two matrix and perform addition of matrix.

In solution matrix given three unknown a, b, & c.we need to find the value of a,b & c.

Firstly we will find the value of a.

Here "a" is first element in second row, so we will add first element of second row from both matrix

-10 - 4 = a

a = -14

Now we will find the  value of b

3 - 12 = b

b = -9

Now we will find the  value of c

- 9 - 3 = c

c = -12

Final answer is:

a = -14

b=-9

c = -12

the answer is two. hope this !
