The experession is:
[tex]-\frac{6}{5}-\frac{2}{3}v+\frac{4}{15}+\frac{1}{3}v[/tex]
In this case, we can multiply the first fraction by 3/3, and reorganice like:
[tex]\begin{gathered} -\frac{6}{5}\frac{3}{3}-\frac{2}{3}v+\frac{4}{15}+\frac{1}{3}v \\ -\frac{18}{15}+\frac{4}{15}-\frac{2}{3}v+\frac{1}{3}v \end{gathered}[/tex]
and we can sum the fraction with common denominator:
[tex]-\frac{14}{15}-\frac{1}{3}v[/tex]
and thats all we can simplify it
