    B and a

    barry=b

    a=older bro

    a is 3 more than 3b

    a=3+3b

    sum is 28

    a+b=28

    3+3b+b=28

    3+4b=28

    minus 3 both sides

    4b=25

    divide both sides by 4

    b=6.25

    a=3+3b

    a=3+3 (6.25)

    a=3+18.75

    a=21.75

    barry=6.25 years

    21.75 years=older bro
