    One month of gameplay costs $15

    Step-by-step explanation:

    Angie: 20 + 3x

    Kenny: 20 + 2x

    (20 + 3x) + (20 + 2x) = 115 - - - add their costs together

    (20 + 20) + (3x + 2x) = 115 - - - collect like terms

    40 + 5x = 115 - - - simplify

    5x = 75 - - - subtract 40 from both sides

    x = 15 - - - divide both sides by 5
