2y+15/y(1-3) X 1/1

2y+15/y "little lost"

How do I get "2/y" for my answer

Answer 1

\[\frac {4y + 30}{y^2 - 3y} * \frac {y - 3}{2y + 15}\]

Answer 2

\[\frac {4y + 30}{y(y - 3)} * \frac {y - 3}{2y + 15}\]

Answer 3

\[\frac {4y + 30}{y} * \frac {1}{2y + 15} = \frac {4y + 30}{y(2y+15)}\]

Answer 4

\[\frac {4y + 30}{y(2y+15)} = \frac {2(2y+15)}{y(2y+15)} = \frac {2}{y}\]
