Q ii) solve for y again using subsitution y=z−21, where z=z(t) is a new dependent variable.
This is where I'm totally stuck and I have absolutely no idea how to solve part ii. I know you need to use the chain rule for y=z−21, however, even here I'm unsure what to do with it.

Could someone solve this please?
y=z−21→dtdy=−21z−23dtdz Then substitute and separate the variables
