    Beth is 5 years younger than celeste. Next year, their ages will have a sum equal to 57. How old is each now?

    Let b = Beth's age
    Let c = Celeste's age

    We are given:
    1. b = c - 5
    2. b + 1 + c + 1 = 57
    Substitute (1) into (2)
    (c - 5) + 1 + c + 1 = 57

    Group like terms:
    2c - 3 = 57

    Type 2c - 3 = 57 into our search engine, we get c = 30

    Substitute c = 30 into Equation (1), we get:
    b = 30 - 5
    b = 25

    Therefore, Beth is 25 and Celeste is 30.
