Answer :

A

By comparing L.H.S and R.H.S


x - y = -1 -------- i


2x – y = 0 -------- ii


2x+ z = 5 --------- iii


3z + w =13 ------- iv


Using i in equation ii


x = -1 + y


ii becomes, -2 + 2y –y = 0


y = 2


x = 1


Putting x in iii


2 + z =5


z = 3


Putting z in iv


9 + w = 13


w = 4
