Let [x] denote the greatest integer less than or equal to x. Let x and y satisfy the simultaneous equations

y = 2[x] + 2

y = 3[x - 2] + 2.

If x is not an integer, then x + y is

• Y-2[X]=1
  Y-3[X]= -4
  SOLVING WE GET [X]=5
  AND Y =11
  ADDING [X]+Y=16

• y = 2[x] + 2
  y = 3[x - 2] + 2
  2[x]+2=3[x - 2] + 2
  2[x]+2=3[x]-6+2
  [x]=6
  so y=14
  so x+y lies in[20,21)

• y = 2[x] + 2
  y = 3[x - 2] + 2
  2[x]+2=3[x - 2] + 2
  2[x]+2=3[x]-6+2
  [x]=6
  so y=14
  so x+y lies in[20,19)
