Question

A (a-2b)-(3b+a) упростить выражение

Answer 1

$(a-2b)-(3b+a) =a-2b-3b-a= -5b$

Answer 2

(a-2b)-(3b+a)=a-2b-3b-a=-5b

Answer 3

To simplify the expression A = (a - 2b) - (3b + a), follow these steps:

1. Distribute the negative sign inside the second parenthesis: A = (a - 2b) - 3b - a

2. Combine like terms: A = a - a - 2b - 3b

3. Simplify further: A = -5b

The simplified expression is A = -5b.
