    The answer to your question is: 8 drinks and 7 candies.

    Step-by-step explanation:

    Data

    Adam bought $76

    Drinks cost = $6

    Candy cost = $4

    Total objects cost = 15

    drinks = ?

    candies = ?

    Process

    1. - Asign letters to each object

    candies = c

    drinks = d

    2. - Write equations with the data given

    c + d = 15

    6d + 4c = 76

    3. - Solve the system equations by elimination

    -4c - 4d = - 60

    4c + 6d = 76

    0 + 2 d = 16

    d = 16/2

    d = 8

    4c + 6 (8) = 76

    4c + 48 = 76

    4c = 76 - 48

    4c = 28

    c = 28/4

    c = 7

    Adam bought 8 drinks and 7 candies.
