a)

\color{blue}{  \frac{2}{3}  =  \frac{a}{6}  + 1\times(6)}  \\ \color{blue}{4 =a + 6}   \\ \color{blue}{a =6 - 4} \\ \colorbox{red}{\color{blue}{a = 2}}

b)

\color{blue}{5=a+\frac{2}{3} \times (3)} \\ \color{blue}{15=3a+2}  \\ \color{blue}{3a = 15 - 2}  \\ \color{blue}{3a =13}

\color{blue}{a =  \frac{13}{3} }\color{green}{ \checkmark}

c)

\color{blue}{\frac{2e}{3}+1=e+2 \times (3)} \\ \color{blue}{2e+3=3e+6} \\ \color{blue}{3e - 2e = 3 - 6} \\ \colorbox{black}{\color{cyan}{e =  - 3}}

\color{blue} {\mathfrak{Dúvidas? \:comente!}}
