Question

Find the value of A+B+C​

Answer 1

Step-by-step explanation:

ANSWER

[

a−b

2a−b

2a+c

3c+d

]=[

−1

0

5

13

]

As the two matrices are equal, their corresponding elements are also equal.

Comparing the corresponding elements, we get:

a−b=−1 .....(1)

2a−b=0 .....(2)

2a+c=5 .....(3)

3c+d=13 .....(4)

From (2), we have

b=2a

Then , from (1), we have:

a−2a=−1

⇒a=1

⇒b=2

Now, from (3), we have:

2×1+c=5

⇒c=3

From (4), we have:

3×3+d=13

⇒9+d=13⇒d=4

∴a=1,b=2,c=3,andd=4
