Which expression shows the first step in simplifying 2x – 3(x + 2y) – 5(y – 7x)?
2 answers:
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:
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
