    y = - 6/5

    Step-by-step explanation:

    Remove parentheses

    2y - 2 - 7y = 4

    group like terms

    2y - 7y - 2 = 4

    add similar elements

    -5y - 2 = 4

    add 2 to both sides

    -5y - 2 + 2 = 4 + 2

    simplify

    -5y = 6

    divide both sides by - 5

    -5y : - 5 and 6 : - 5

    simplify

    y = - 6/5
