The present time is putting forward the need of self learning and real help offered by me.

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) a - b = -1 and 2a - b = 0; solving a =1 and b = 2 2a + c = 5, substituting...

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)

a - b = -1 and 2a - b = 0; solving a =1 and b = 2

2a + c = 5, substituting a = 1, c =  

3c + d = 13, substituting c =  ;  d =

I am expert in electrical engineering . I have b tech and m tech from nit warangal total experi 10 y

a-b=-1, 2a+c=5, 2a-b=0, 3c+d=13 Solve eq 1 and 3 or put the valve of a in eg one and substitute value of b in eg three or put the value of c in fourth then we get A=1,b=2, c=3,d=4 this ans

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

Comparing the corresponding elements, we get:

ab = −1 … (1)

2ab = 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, and d = 4

If a matrix has 24 elements, what are the possible orders it can have? What, if it has 13 elements?
24 = 1 X 24 = 2 X 12 = 3 X 8 = 4 X 6 = 6 X 4 = 8 X 3 = 12 X 2 = 24 X 1 So, there are 8 orders possible. Similarly 13 = 1 X 13 and 13 X1, So, only 2 orders are possible.
