let the number be x and x + 1.
if the sume of their ages is 25, then x + x + 1 = 25.
combine like terms to get 2x + 1 = 25
subtract 1 frm both sides of this equation to get 2x = 24
solve for x to get x = 12
their ages are 12 and 13.
the sum of their ages is 25.
solution looks good.
the age of the younger friend is 12.
