You can put this solution on YOUR website!
let f = your father's age today.
let s = your age today.

f = 3s

this means your father's age is 3 times your age today.

f = s + 28

this means your father is 28 years older than you.

replace f in the second equation with 3s from the first equation to get:

3s = s + 28

subtract s from both sides of the equation to get 2s = 28

solve for s to get s = 14

that's your age today.

f = 3s = 42

that's your father's age today.

you were both 14 years ago.

your father was 42 - 14 = 28 years old at the time.

solution looks good.

your father is 42 and you are 14 today.
