$T=\frac{175}{28}~\ln (1-\frac{V}{35})$

$\ln (1-\frac{V}{35})=\frac{28}{175}T$

$\log_e (1-\frac{V}{35}) = \frac{28}{175}T$

Hint :

$\log_a b = c \rightarrow b=a^c$

You can solve the rest questions using the same hint

35(((28/175T)/ln)+1)=-V
I don't think your answer is right. Continuing my work and using the hint given :

$\log_e (1-\frac{V}{35}) = \frac{28}{175}T$

$1-\frac{V}{35}=e^{\frac{28}{175}T}$
