This is me (Cbx) testing math.

$A:{\frac {V_{b}-V_{a}}{10}}+{\frac {V_{b}-V_{c}}{30}}+{\frac {V_{b}-V_{d}}{20}}+1A=0$

$B:{\frac {V_{a}-V_{b}}{10}}+{\frac {V_{c}-V_{b}}{30}}+{\frac {V_{d}-V_{b}}{20}}+1A=0$

$C:{\frac {V_{b}-V_{a}}{10}}+{\frac {V_{b}-V_{d}}{20}}=0$

$D:{\frac {V_{b}-V_{a}}{10}}+{\frac {V_{b}-V_{c}}{1A}}+{\frac {V_{b}-V_{c}}{30}}+{\frac {V_{b}-V_{d}}{20}}=0$
