Раскройте скобки и упростите выражения: 1) 5m+(7m- (2m-3)=2) 2 (m+1)+(6m+(2-4m)=3) (3m-7)+(2m- (5+(4-m)=4) (2 (m-1)…

1) 5m+(7m- (2m-3)=5m+(7m-2m+3)=10m+32) 2 (m+1)+(6m+(2-4m)=2m+1+(6m+2-4m)=4m+33) (3m-7)+(2m- (5+(4-m)=3m-7+(2m- (5+4-m)=3m-7+(2m-9+m)=6m-164) (2 (m-1) -1)+(2m+(1- (2-m)=(2m-2) -1)+(2m+(1-2+m)=2m-3+3m-1=5m-45) 1+(m- (1+(m- (1+m)=1+(m- (1+(m-1-m)=1+(m-1)=m
