Find the value of a if

Given:

To find: value of a

Firstly, we equate the corresponding elements, we get

a – b = -1 …(i)

2a + c = 5 …(ii)

2a – b = 0 …(iii)

and 3c + d = 13 …(iv)

Solving eq. (iii), we get

2a = b

Substitute the value of ‘b’, in eq. (i), we get

a – 2a = -1

⇒ -a = -1

⇒ a = 1

Hence, the value of a = 1
