    Work inside the parenthesis first:
    2(y - 2y + 3y) - 4 = 8 - 1(92y - y - y) + 1012

    2(2y) - 4 = 8 - 1(90y) + 1012

    4y - 4 = 8 - 90y + 1012

    4y - 4 = 1020 - 90y

    4y - 4 + 90y = 1020 - 90y + 90y

    94y - 4 = 1020

    94y - 4 + 4 = 1020 + 4

    94y = 1024

    \frac{94y}{94} = \frac{1024}{94}

    y = \frac{1024}{94} = \frac{512}{47}
