    Solve for Y


    -4y - 5/3 = 1/3y - 2/5
    Simplify as much as possible.

    I'm having a bit of trouble with this. This is what I've got so far.

    -12y -5 = y -6/5

    -y           -y
    -13y- 5 = -6/5
      + 5         +5
    -13y = 3 4/5
    Is it correct?

    Re: Solve for Y

    It's almost correct (check the last part again:  \frac{-6}{5}+5=...), I will rewrite it with latex codes:
    -4y-\frac{5}{3}=\frac{y}{3}-\frac{2}{5}
    You can also multiply all the term with 15, why 15? Because that's the LCM of 3 and 5.
    Therefore you get:
    -60y-25=5y-6
