The given expression is:
[tex]11\text{ + (-5) - }\frac{4}{5}j\text{ - 2 - 5j + 7}[/tex]Collect like terms:
[tex]\begin{gathered} 11\text{ - 5 - 2 + 7 - }\frac{4}{5}j\text{ - 5j} \\ 11\text{ - }\frac{4}{5}j\text{ - 5j} \end{gathered}[/tex]This can be further simplified to be:
[tex]\begin{gathered} \frac{55-4j-25j}{5} \\ \frac{55-29j}{5} \end{gathered}[/tex]
