If 2x+3y+z=25 & 3x+2y+2z=24,If x,y & z are integers,find x+y+z=?

• the give equation has 3 variables and two equation so there are infinitely many solutions.
  let x =2t solve equation for y and z.
  we get y= (13-t)/2
  and z= (11-5t)/2
  ===> x+y+z = 12-t
  put t= {....-3,-1,1,3...} only odd integers.
  w3 get x+y+z={...15,13,11,9.....}
