Помогите решить несколько примеров!!! с - ( a + b ) =
-c- ( - a + b )
x - ( a - b ) +( c - d ) =
10 - ( a- b ) - ( c + d ) =
-(8c - 4 ) + 4 =
( 5 - 4) - ( 2 + 5a - 3b ) =
5b - ( 6b + a ) - ( a - 6b ) =
-c- ( - a + b )
x - ( a - b ) +( c - d ) =
10 - ( a- b ) - ( c + d ) =
-(8c - 4 ) + 4 =
( 5 - 4) - ( 2 + 5a - 3b ) =
5b - ( 6b + a ) - ( a - 6b ) =
