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)+(2m+(1-(2-m)))= 5)1+(m-(1+(m-(1+m))))=

1)5m + ( 7m - ( 2m - 3 )) = 5m + ( 7m - 2m - 3) = 5m + (  5m - 3 ) = 5m + 5m - 3 = 10m - 3.

2)2 ( m + 1 ) + ( 6m + ( 2 - 4m )) = 2m + 2 + ( 6m + 2 - 4m ) = 2m + 2 + ( 2m + 2 ) =

2m + 2 + 2m + 2 = 4m + 4.

3)( 3m - 7 ) + ( 2m - ( 5 + ( 4 - m ))) = 3m - 7 + ( 2m - ( 5 + 4 - m )) = 3m - 7 + ( 2m -( 9 - m ))= = 3m - 7 + ( 2m - 9 + m  ) = 3m - 7 + ( m - 9 ) = 3m - 7 + m - 9 = 4m - 16.

4) (  2 ( m - 1 ) - 1 ) + ( 2m + ( 1 - ( 2 - m ))) = ( 2m - 2 - 1 ) + ( 2m + ( 1 - 2 + m )) = 2m - 3 + 

+ ( 2m + ( m - 1 )) = 2m - 3 + ( 3m - 1 ) = 5m - 4.

5) 1 + ( m - ( 1 + ( m - ( 1 + m )))) = 1 + ( m - ( 1 + ( - 1 ))) = 1 + ( m - ( 0 )) = 1 + m.
