Помогите!! Спростить выраз 2(a+b)-2a

2а+2в-2а=2а-2а+2в=2в

Answer 2

I can help you with simplifying expressions. To simplify the expression 2(a+b)-2a, you need to follow these steps:

- Apply the distributive property of multiplication over addition to 2(a+b) and get 2a+2b. - Rewrite the expression as 2a+2b-2a. - Combine the like terms 2a and -2a and get 0. - Simplify the expression further by removing the zero term and get 2b.

The final answer is 2b. Here is the solution in LaTeX:

$$ \begin{aligned} 2(a+b)-2a &= 2a+2b-2a && \text{(distributive property)} \\ &= (2a-2a)+2b && \text{(commutative property)} \\ &= 0+2b && \text{(combine like terms)} \\ &= 2b && \text{(identity property)} \end{aligned} $$

I hope this helps you understand how to simplify expressions. If you have any other questions, feel free to ask me.Ответь+подробно.+Помогите!!+Спростить+выраз+2(a+b)-2a
