Find the eqn of the plane passing through the point 2i-2j+2k and all parallel to the plane r.(2i-4j+2k)=5

Dear LINTA

equation of plane parallel to r.(2i-4j+2k)=5  is

  r.(2i-4j+2k)=d

this plane passes through  2i-2j+2k so

 (2i-2j+2k).(2i-4j+2k)=d

d = 4+8+4 =16

so desired plane r.(2i-4j+2k)=16
