$Default$ Really simple question

I have to rearrange the formula T-xy=3yz^2 to make y the subject. I know i shuold be able to do it but i just have a mental block. If someone can go through the stages it'd be much appreciated.

$T-xy=3yz^2$

$T=3yz^2 + xy$

$T=y(3z^2 + x)$

$\frac{T}{3z^2 + x} = y$

is that right?
