?

Answer 13

Hmm?

Answer 14

combine like terms
\[\huge\rm \color{green}{a} + 2\color{blue}{c} - 5\color{Red}{b} -\color{blue}{ c} + \color{green}{a} - \color{red}{b}\]
add coefficient of a
add coefficient of b variables
for example a + a can be written as 1a+1a = (1+1)a which is 2a
now try b and c terms
