Question

Раскрыть скобки и привести подобные слагаемые:6b-(9a-2b)+(3a-10b)=

Answer 1

6b-9a+2b+3a-10b=-6a-2b

Answer 2

To simplify the expression and combine like terms, let's start by expanding the parentheses and then combining the similar terms:

6b - (9a - 2b) + (3a - 10b)

First, distribute the negative sign to the terms inside the first set of parentheses:

6b - 9a + 2b + (3a - 10b)

Now, distribute the positive sign to the terms inside the second set of parentheses:

6b - 9a + 2b + 3a - 10b

Now, let's combine the like terms:

(6b + 2b - 10b) + (-9a + 3a)

Combine the "b" terms:

(6b + 2b - 10b) = -2b

Combine the "a" terms:

(-9a + 3a) = -6a

So the simplified expression becomes:

-2b - 6a
