Answer:
2n - 2
Step-by-step explanation:
rewrite without parentheses, pretend there is a 1 between the minus sign and the open parentheses that has to be distributed:
3n - 1(2 + n)
3n - (1)(2) + (-1)(n)
3n - 2 - n
combine 3n and -n to get 2n
[tex]2n - 2[/tex]
When there is a - in front of an expression in parentheses, change the sign of each term in the expression:
[tex]3n - 2 - n[/tex]
Combine like terms:
[tex]3n - n - 2 \\ 2n - 2[/tex]
