It's simple, there is a ton
Multiply all the numbers by 2: 20m - 80
or Divide all the numbers by 2: 5m- 20
or Multiply all the numbers by 3: 30m - 120
The answer is on the picture!!
Order of Operations, also known as PEMDAS (Parentheses, Exponents, Multiplication & Division, Addition & Subtraction), can help to simplify an equation by guiding you through the steps to solve it.
This is because it tells you to solve the parentheses. If there is none, but you've already done this, you solve for exponents, etc.
The progressive soling of the equation not only makes it physically shorter, but also brings you closer to the answer.
Hope this helps, and I was the brainliest! :)
Remove unnecessary parenthesis.
-5k 3 - 6k +1 - 6k 2 + 5k (simplify each term) -15k - 6k + 1 - 12k +5k = -28k +1
Answer: 28k + 1
