Question : Find No. of values of X for which (2X+9)/(X+3) is an integer

• 4 solution x= -4 , -2 ,0 , -6
• 8 years agoHelpfull: Yes(10) No(0)
• x=0,-2,-6
  three solution
• 8 years agoHelpfull: Yes(3) No(1)
• For x=0, (2*0 +9)/(0+3)=3 ans
• 8 years agoHelpfull: Yes(2) No(1)
• x=0 and -2
• 8 years agoHelpfull: Yes(1) No(0)
• let t be a integer
  (2x+3)/(x+3)=t
  (2x+3)/(x+3) -2=t-2 //subtracting 2 from both side
  3/(x+3)=t-2
  as rhs is integer
  for lhs to integer deno. should be 3,1,-3 which possible when x=0,-2,-6
  so nos of solution = 3

• 2x+9=(x+3)+(x+3)+3
  3/(x+3) is to be determined only..
  x=! -3
  x=0,3,-1,-2,-4,-5,-6,-9
  so there are 8 possible values of x
