Answer:
The simplified solution is [tex]3n-3[/tex]
Step-by-step explanation:
we need to simplify the expression [tex]n-{1-[n-(1-n)-1]}[/tex]
First, open the inner bracket
⇒[tex]n-{1-[n-1+n-1]}[/tex]
⇒[tex]n-{1-n+1-n+1}[/tex]
⇒[tex]n-1+n-1+n-1[/tex]
combine the like terms,
⇒[tex]n+n+n-1-1-1[/tex]
⇒[tex]3n-3[/tex]
Hence, the simplified solution is [tex]3n-3[/tex]
