    Answer:

    y = -11

    Step-by-step explanation:

    y – 3 (2y – 7) = 76

    distribute the three to the two values in the parenthesis!

    y – 6y + 21 = 76

    now combine like terms, baiscally add y to -6y

    -5y + 21 = 76

    now subtract 21 from both sides

    -5y = 55

    then divide by negative 5

    y = -11
