PLease help.

Answer 1

V - E+F = 2

i tried it but i get confused... it never equals two

Answer 3

\[\Large\rm \color{orangered}{V=13}, \qquad \color{royalblue}{E=28}\]
\[\Large\rm \color{orangered}{V}-\color{royalblue}{E}+F=2\]So you plug in your values, ya?\[\Large\rm \color{orangered}{13}-\color{royalblue}{28}+F=2\]
