Answer 2

Пошаговое объяснение:

-(5a-6b)-(4b-3a)-(7a-2b)=

=-5а+6b-4b+3а-7а+2b=

=(-5+3-7)a+(6-4+2)b= -9a+4b

Answer 3

To simplify the expression -(5a-6b)-(4b-3a)-(7a-2b), let's expand and combine like terms:

-(5a-6b) = -5a + 6b -(4b-3a) = -4b + 3a -(7a-2b) = -7a + 2b

Now, let's substitute these expressions back into the original equation:

-5a + 6b - (-4b + 3a) - (-7a + 2b)

Distribute the negative sign:

-5a + 6b + 4b - 3a + 7a - 2b

Combine like terms:

(-5a - 3a + 7a) + (6b + 4b - 2b)

Simplify:

-1a + 8b

Therefore, the simplified expression is -a + 8b.
