    If that's meant to me -3(y-2)-y=5 then you just multiply out those brackets to get...

    -3y+6-y=5

    Then collect the y terms to get...

    -4y+6=5

    Take the 6 across to the other side to get...

    -4y=-1

    And finally dividing by -4 you get...

    y=\frac{1}{4}

    Have no fear, the calvary is here!

    -3(y-2)-4=5

    First distribute the -3 on the left side

    -3y+6-4=5

    Now, combine terms on the left

    -3y+2=5

    Next, subtract 2 from both sides

    -3y=3

    Finally, divide both sides by -3

    y=-1

    Ta-Da!!

    -3(y-2)-y=5
    -3y+6-y=5
    -3y-y=5-6
    -4y=-1
    now finish up

    There is no 4 in the original equation.
