I don't know the answer so u can take the help of Google app..m

Answer 2

Answer:

Step-by-step explanation:

a+b-c= substituting values

            = ( x-2y+z)+ (2x+y+z)- (x+y-2z)

           =x-2y+z+2x+y+z-x-y+2z

           = x+2x-x-2y+y-y+z+z+2z

           = 2x-2y+4z

            = 2(x-y+2z)

You can let me know that if have to do again any steps for this or it is sufficient
