hope it helps :)
Answer:
3n - 4m
Step-by-step explanation:
(2n-5m)+(n+m)
so we get this equation and from here, we expand the equation by removing the brackets, you should get:
2n-5m+n+m and just solve from here.
to make it easier, put the like terms together:
2n+n+m-5m
= 3n-4m
Example
6.
3/8+1/4+__=1
1/4 is the same like 2/8
3/8+2/8=5/8
5/8+__=1
1 is the same like 8/8
5/8+__=8/8
8/8-5/8=_
8/8-5/8=3/8
Blank field-> 3/8
