How do I solve this? Thanks

Question 1:
Vf = Vo + at
Find Vo

Question 2:

P1V1 = P2V2
Find V1

The Attempt at a Solution

Vo = at - vf

I'm new to taking Physical Science. Could someone help me on understanding how to solve the above problems. I got stuck on the second one. Thanks.

i cant understand what you are asking

The question is Vf = Vo + at
I got to find Vo

Ummm ... just rearrange them???

VolsDoll82
Vo = at - vf

is what I got by isolating variables.

Rearrange correctly

it must be: Vo = Vf - at
