Answer: Option 3.


Step-by-step explanation:

1. To simplify the expression shown in the problem, the first step is to apply the Distributive property, this means that you must multiply the number that are outside of the parentheses by the numbers inside of them.

2. Then, you have that the first step is:

2x-3(x+2y)-5(y-7x)=2x-3x-6y-5y+35x

3. Therefore, you can conclude that the correct answer is the third option.

Answer:

2x - 3x - 6y -5y + 35x

Step-by-step explanation:

2x-3(x+2y)-5(y-7x)

We use order of operations PEMDAS

Lets start with parenthesis

We distribute -3 inside the parenthesis and Distribute -5 inside the parenthesis

2x - 3x - 6y -5y + 35x

combine like terms

-1x - 6y -5y + 35x

-1x - 11y + 35x

34x - 11y

first step is 2x - 3x - 6y -5y + 35x
