    Walt = 48 years

    Ralph = 45 years

    Henry = 41 years

    Step-by-step explanation:

    We know that Walt is 3 years older than Ralph so we can write,

    Walt = 3 + Ralph eq. 1

    We also know that Ralph is 4 years older than Henry so we can write,

    Ralph = 4 + Henry eq. 2

    It is given that Walt's age is 48 years so substitute it into eq. 1

    Walt = 3 + Ralph

    48 = 3 + Ralph

    Ralph = 48 - 3

    Ralph = 45 years

    Now substitute the age of Ralph into eq. 2

    Ralph = 4 + Henry

    45 = 4 + Henry

    Henry = 45 - 4

    Henry = 41 years

    Therefore,

    Walt = 48 years

    Ralph = 45 years

    Henry = 41 years

    Verification:

    Walt = 3 + Ralph eq. 1

    48 = 3 + 45

    48 = 48 satisfied

    Ralph = 4 + Henry eq. 2

    45 = 4 + 41

    45 = 45 satisfied

    Ralph is 45 and Henry is 41

    Step-by-step explanation:

    if Walt is 48 to find Ralph you subtract 3 because Walt is 3 tears older than Ralph.

    to find Henry you subtract 4 from Ralph and get 41
