Question

xyz + xy + xz + yz + x + y +z=1000 then the value of x+y+z is​

Answer 1

Answer:

xyz+xy+xz+yz+x+y+z=1000 then x+y+z=988 I think so

Steps

xyz+xy+xz+yz+x+y+z=1000

4x+4y+4z=1000

Keeping all variables on one side and digits on the other side

x+y+z=1000-4-4-4

x+y+z=1000-12

x+y+z=988

Hope this helps
