Changing the subject in an equation
I know how to change the subject of the formula in an equation like u=v+2t, but I get confused when the equation is for example p=5xyz+5ab^2 making x the subject.
This is the answer I got:
p - 5ab^2= 5xyz
p - 5ab^2/5yz= x
x = p - 5ab^2/5yz
Was wondering if i could get some advice on whether the answer is correct and my steps as to how I got it are correct because I have a feeling I have made a mistake.
Thank you (Nod)

parentheses around your numerator and denominator ...
