3m- [2n- { mn- ( m- n + mn ) + mn} + n] -m​

Answer 1

Answer:

3m-(2n-(mn-(m-n+mn)+mn)+n)-m

=3n-(2n-(mn-m+n-mn+mn)+n)-m

=3n-(2n-(-m+n+mn)+n)-m

=3n-(2n+m-n-mn+n)-m

=3n-(2n+m-mn)-m

=3n-2n-m+mn-m

=n-2m+mn

Answer 2

Step-by-step explanation:

3m-[2n-{mn-m+n-mn+mn}+n]-m

3m-[2n-mn+m-n+n]-m

3m-2n+mn-m-m

3m-2m-2n+mn

m-2n+mm
