    First, find the least common denominator.

    Left is 12, right is 5.

    5 x 12 = 60 For this case is the lowest.

    why would I subtract 40? That confuses me

    \[\frac{ 3y - 8 }{ 12 } - \frac{ y }{ 5 }\] \[= \frac{ y }{ 5 } - \frac{ y }{ 5 } = 0\]

  21. Defiance

    Subtract y / 5 from both sides.

    we wouldn't be subtracting y from the 3y up top and the 5 from the 12 down below?

    would I subtract 15y to isolate the y on the on the 12y side?

    Move the 12y over to the 15y. To get \[15y -12y = 40\]

    Move the 3 back to the 40 to make the faction.
