We are given the following expression
[tex]2w-5(-2z+2w)-5z[/tex]Let us simplify the above expression
Step 1:
Expand the parenthesis
[tex]\begin{gathered} 2w-5(-2z+2w)-5z \\ 2w+10z-10w-5z \end{gathered}[/tex]Step 2:
Combine the like terms
[tex]\begin{gathered} 2w+10z-10w-5z \\ 2w-10w+10z-5z \\ -8w+5z \end{gathered}[/tex]Therefore, the simplified expression is
[tex]-8w+5z[/tex]
