Ayuden plis!!!. es urgente!
1) 8m-(-5m)=
2) 2m- (7m)=
3) (4m+2n) - (5m+4n)=
4) (3m+2n)-(6m+4n)=
5) 2m-5n)-(-3m+2n)=
6) (8m-3n) - (5m-4n)=
7) (7m-5n) - (-5m+5n)=
8) (2m+3n)-(-3n+4m)=
9) (4m+3n)-(2m-5n)=
10) (6m+5n)-(-3m+8n)=

2.- 2m-7m = -5m
3.- 4m+2n-5m-4n =-m-2n
4.- 3m+2n-6m-4n= -3m-2n
5.- 2m-5n+3m-2n = 5m-7n
6.- 8m-3n-5m+4n= 3m+n
7.- 7m-5n+5m-5n = 12m-10n
8.- 2m+3n+3n-4m = -2m+6n
9.- 4m+3n-2m+5n = 2m+8n
10.- 6m+5n+3m-8n = 3m-3n
