Help me with this attachment please?

Answer 1

The three solutions are:

• 
  `a = 1,\ b = 3`. In fact,
  `1+333+333+333 = 1333`
• 
  `a = 2,\ b = 6`. In fact,
  `2+666+666+666+666 = 2666`
• 
  `a = 3,\ b = 9`. In fact,
  `3+999+999+999+999 = 3999`

You can find the first one with a bit of trial and error. The second and third derive from the fact that if you multiply by 2 or 3 every term, the whole result will be multiplied by 2 or 3 as well
