m-m+n-\left(m-n\right)=2n-m
To find the opposite of m-n, find the opposite of each term.
n-\left(m-n\right)=2n-m
Combine m and -m to get 0.
n-m+n=2n-m
To find the opposite of m-n, find the opposite of each term.
2n-m=2n-m
Combine n and n to get 2n.
2n-m+m=2n
Add m to both sides.
2n=2n
Combine -m and m to get 0.
n=n
Cancel out 2 on both sides.
\text{true}
Reorder the terms.
m\in \mathrm{C}
This is true for any m.
m-m+n-\left(m-n\right)=2n-m
To find the opposite of m-n, find the opposite of each term.
n-\left(m-n\right)=2n-m
Combine m and -m to get 0.
n-m+n=2n-m
To find the opposite of m-n, find the opposite of each term.
2n-m=2n-m
Combine n and n to get 2n.
2n-m-2n=-m
Subtract 2n from both sides.
-m=-m
Combine 2n and -2n to get 0.
m=m
Cancel out -1 on both sides.
