Please help!! Andy is 2 year older than jeff. in 5 years the sum of their ages will be 40 years . find their ages now .... provi

ANTONII [103]

Andy's age = x
Jeff's age    = x-2
Andy's age in five years = x+5
Jeff's age in five years    = x-2+5
The sum of their ages in five years = x+5 + x-2+5

   x + 5 + x - 2 + 5 = 40
   2x + 8 = 40
   <u> -8 -8</u>
      2x = 32
     <u> :2 :2</u>
   x = 16
x - 2 = 14

<u>Andy is 16 years old and Jeff is 14 years old</u>
