If x-y + z = 19 , y + z =20, x-z=3,

solving these, we get
x=15,y=8, z=12

x+4y -5z= 15+32-60 = -13 .. none of these.

x-y+z=19---------(1)
y+z=20
thus y=20-z---------(2)
x-z=3
thus x =3+z---------(3)
substitute x and y in equation (1)
you will get,
(3+z) - (20-z) + z = 19
3z = 36
z = 12
substitute z in (2) and (3)
thus x = 15
and y = 8
substitute value of x,y,z in x+4y-5z
answer is - 13.... none....

add all three eq u will get 2x+z=42
then find x=15
then find z=12
thn find y=8
so x+4y-5z=15+4*8-5*12
15+32-60
47-60=-13

on simplification of equations we got x=15,y=8,z=15
on submitting value is=-13
so ans is none of these.
