Question

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 ) =

Answer 1

C – (a + b) = c – a – b;
–c – (–a + b) = –c + a – b;
x – (a – b) + (c – d) = x – a + b + c – d;
10 – (a – b) – (c + d) = 10 – a + b – c – d;
–(8c – 4) + 4 = –8c + 4 + 4 = –8c + 8 = 8 × (1 – c);
(5 – 4) – (2 + 5a – 3b) = 1 – 2 – 5a + 3b = 3b – 5a – 1;
5b – (6b + a) – (a – 6b) = 5b – 6b – a – a + 6b = 5b – 2a

Огромное тебе спасибо!!!

Answer 2

C-a-b
-c+a-b
x-a+b+c-d
10-a+b-c-d
-8c+8
-1-5a-3b
5b-2a
