Ответ:
Let k = Ken's age.
We know that Frank is 3 times as old as Ken, so Frank = 3k.
We know that Ken is 1 year younger than Eileen. This means that Eileen is 1 year older than Ken, and Eileen = k+1.
Frank is 15 years older than Eileen, so Frank is (k+1)+15.
This gives us two expressions for Frank; we can set them equal to form an equation to solve:
3k = (k+1)+15
Combine like terms on the right:
3k = k+16
Subtract k from both sides:
3k-k = k+16-k
2k = 16
Divide both sides by 2:
2k/2 = 16/2
k=8
Ken is 8.
Frank is 3*8 = 24.
Eileen is 8+1 = 9.
